    ES-345 what cable do I use?

    Do I need a stereo to mono cable? How easy are these to make?
    Any tips?

    Re: ES-345 what cable do I use?

    Depends. Some, but not all, 345s, have the pickups wired out-of-phase. Simply summing them with a stereo to mono cable makes it sound really thin.

    Some 345s will work in mono if you simply push the jack of a standard cable in half way. In Arlington last week, we did that with one and it worked fine. Another did not. I have had several in the past that worked fine that way, some in phase, some out. One highly respected vintage restoration guru who was there believes they all should work that way and if they don't, it is due to a worn, bent jack.

    You can use a TRS stereo jack split to two mono TS jacks and plug into two amps or two channels of one amp. But again, phasing is something you have to deal with. Fender channels are OOP so if the pickups are OOP, that solution brings them back in phase.

    Another solution, albeit controversial, is to pull the varitone and wire it like a 335. But I won't start that discussion. Oops, maybe I just did.

    Re: ES-345 what cable do I use?

    Best solution is a Gibson GA 79 and a stereo to stereo cable. Failing that, the Y-cable splitting the output to 2 channels. I use a Fender tweed Tremolux or tweed Deluxe that way and it works great with no phase issues at all with a bone stock 345. No mention of Varitone necessary for this discussion.

    I was in on that little test. An LPF member bought a really nice '59 345 that happened to have its original factory stereo cable and original strap (very cool). Michael Minnis was playing it and we decided to dig the stereo cable out of the case and give it a try. In the picture below, you can see the factory gray stereo cable plugged into the guitar. We then plugged each output into the two amps I brought to the show. That was kind-of cool.

    But what triggered that little test? That particular 345 wouldn't do both pickups with a mono cable plugged half-way in. Just one pickup.

    Conversely, at the same time, Tom went and grabbed a nearly identical-looking '59 345 from another dealer's booth and brought it over, and that one did work just fine with the mono cable plugged half-way in.

    Strange stuff.

    Re: ES-345 what cable do I use?

    I had "Y" cables made for mine, into 2 channel amps. When you combine both channels with a stereo/mono cable you lose gain and volume.

    My only drawback for using this type of setup is, any effects chain is only on one pu, unless you have stereo effects or you use 2 effect chains.

    Re: ES-345 what cable do I use?

    AFAIK, all ES-345's and 355's are out of phase in the middle position. THe Lucilles are also wired thisway as is the ltd ed B.B. King gutiars...?GC specials??? This out of phase thingis not an undesirable thing to many. B.B. 'stings' with this sound. HEy, Peter Green's Greenie was modded to be out of phase in the middle position. IT is not a 335 sound, though.
    The stereo wiring necessitates one of 3 things...1)a stereo cable with a output plug for each pickup to use into two amps or two channels of one amp. 2)One can also use a two-into-one adapter wtih this stereo cable to bring the two plugs into one output for mon operation.or 3) one canbuild a two-into-one cable---stereo out of the guitar with both leads combined on a mono plug.
    YEs, the Gibson stereo amps are nice. I had a GA-78...non reverb GA-79.
    IT was nice. I keep two SuperCahmps for my '66 ES-345. WIht separate amps, you can spread teh stereo image wider than with a 'contained' stereo amp such as the Gibson Ga78/79's. Gibson did make an earlier stereo amp that had a separate speaker box for one ofhte amps...spread it out.
    RE: FEnder two channe lreverb amps. YEs, their channelsare out of phase, adn when playing one of these Gibsons through the two channels thephase does coem to be in-phase. However, the reason why those amps' channel are out of phase is becasue the Vib channel has an extra gain stage compared to the Norm ch. PErhaps one can balance that aspect out.
    Wtih two identical amps such as my rig withthe Super Champs, you can reverse the wiring on the speaker in one amp. That puts the amps out of phase. Once again....two OOP situations result in being in phase. This is the best solution, imho...if one wants in-phase as opposed to out of phase.

    Re: ES-345 what cable do I use?

    Reinhard, just ot be more direct in answering your question....
    You need:
    1)waulity..I use BElden...two conductor cable with shield cable. Maybe 15-20 feet for the 'stereo' run, plus maybe 10-15 more for the 'mono' runs from the 'Y' where you would separate each conductor from the 'stereo' cable to go 'mono'. IF you are building a 'mono' output, you could make do with whatever lenghth you want the cable to be because you don't have to make the 'mono' runs.
    2)a stereo plug for the guitar.
    3)1 or 2 mono plugs depending on whether you want a stereo output or a mono output.
    3)some good electrical tape to make a good Y junction safe, strong and secure...and neat looking. My cable has been servicing my 345 since I built it in the '70's.
    For a mono cable, you are gonig to wire the stereo plug at the guitar as a stereo plug. At the other end, just take both leads to the tip contact on the plug.
    For stereo, you wire the stereo plug at the guitar as above. At the end of that cable, you are going to take ech lead to the conductor of each 'mono' leg, join the ground/shield, and then fashion a good 'joint' with the tape. Finish the mono cable runs with a mono plug as normal.

    I believe that electronic phase and magnetic phase are not the same thing. It is my understanding-and I'm NOT an engineer, that switching the wires won't do anything but put your amps out of phase. The pickups will still be out of phase unless you flip over a magnet.

    I understand that in changing the speaker leads one is not changing the phase of the relationship of the pickups within the guitar. That said, I just did the experiment. Believe it or not, there is a difference. WIth the amps 'in phase', the middle toggle position on the guitar yields a less powerful sound that does either pickup alone---typical 'out of phase' result, right? When I reversed the lelads to the speaker in one amp---putting the amps out of phase with each other, the middle position is more powerful than either pickup alone. This is the same thing that goes on with the two channel Fender amps.....the channels are out of phase. Run two pickups that are out of phase with each other...one pickup into each channelf of say a Deluxe REverb or any other two channel Fender reverb amp that hasn't been modded to have the reverb on both channels, and the result is that the final sound out of the speaker is typical of pickups that are in phace with each other. IF you run the same ES-345/355 in a mono mode with both pickups in to one channel of that amp, you will hear that out-of-phase thing...less powerful in the middle than on either pickup alone.

    Yep, you can do that. Many have. However, there must be a reason why some folks...B.B. King, Freddie King, and others...have used these stereo/varitone Gibsons and found good effect in doing so. EAch to his own.

    Reversing the speaker leads will have the exact same result as flipping the magnet. Phase is agnostic with regards to what caused it to shift, electronic circuits, transducer polarity or acoustic phenomena. when flipping it (180 degrees) it's out, flipping it again and it's in phase, doesn't matter where in the chain it happens. (This is true for phase shifts of less than 180 degrees as well)
    People claim all kinds of things regarding this topic. my favorite claim is by PU makers who claim they hear a difference listening to ONE PU by itself in phase and out of phase. Those claims are usually met with skepticism because phase shift can only exist between at least 2 PUs. Both have it wrong of course because the entire chain is subject to phase. If you record a single PU direct w/o an amp in the room it won't matter if the PU or any other device in the chain is in phase or not. When you re-amp the signal you can flip phase and it'll sound the same. This is not true when you play amplified. Every owner of an acoustic guitar with PU's knows this, the preamps usually have a phase switch to combat feedback. The guitar will sound different with only one PU active, in phase or out because of the way the soundwaves of the amplified signal interact with the guitar itself, notes that ring free in phase will sound choked off out of phase because, depending on the distance and frequency, the amplified signal might cancel the guitars vibration, etc. electric guitars are subject to this as well, try flipping phase during a harmonic feedback, it'll stop the loop or change it instantly. So, yes a PU will sound different in phase and out even by itself when playing amplified but it doesn't matter how the phase was reversed.
    As far as ripping out the stereo circuit and varitone, that's another topic alltogether. I personally wouldn't do it, varitones have some very nice usable settings, IMO and the word on wether they kill tone is still out, right?

    Re: ES-345 what cable do I use?

    Digging this old thread here. Just bought a '61 ES-345, that works fine with the jack halfway in, so I decided to see if I could just do a stereo to mono cable, no problem. What I did was take a stereo cable, plug it in, and then short the two channels on the amp side. Worked exactly the same as putting a mono jack in halfway, and I can have all the confidence of having it plugged in fully.

    I'm not sure I follow what 'short the two channels on the amp side" means.
    However, building a cable with stereo on one end and the two 'hots' boath connected to a mono plug's tip into the amp on the other end is the way I would go about running a stereo guitar in mono.

    Can't you just take a standard [mono] cable and put a stereo plug on it, with the hot wire going to the two hot terminals on the stereo plug?

    Isn't this a 'mix-down cable?' I think this will "wimpify" the sound. Better results come from using a stero cable at the guitar and then using a Y-splitter at the amp - so long as your amp has two inputs.

    Here's an old post of mine detailing three of my guitars, one of which is a 1959 ES 345 with the varitone intact. The stereo to Y mono mono cable is visible in the picture. There is some discussion about the 345 in this thread. (Warning! The picture is HUGE!)

    http://www.lespaulforum.com/forum/sh...&highlight=345


    It is possible to modify your single channel amp to properly accomodate a stereo input without the sound being "wimpified."

    Here's another old post of mine detailing the cheap, easy, and noninvasive amp modification to get the true 345/355 stero sound from a one input amp. With this modification, there is no issues whatsoever when switching from 345 to LP.

    Re: ES-345 what cable do I use?

    There's a post here somewhere with a photo of a (yellow?)stereo to mono switching/mix pedal.
    I've spent hours trying to find it.
    Can someone repost that pic, or post a link?
    That seems like the best solution for those wanting to plug a 345 or similar stereo guitar into a single input/single channel amp.

    Re: ES-345 what cable do I use?

    Naturally i have my original y cable, black and red ends. but a few years ago Brian Moore guitars were getting into the usb deal and must have sold off a lot of their Y cables. Top quality cables and i bought a few, excellent. I got them off of ebay and i'd search for them or another y cable. I like using two amps, put delay on one pickup, a slight over drive, fuzz or wah on the other. Play the middle position on any selection, many great tones available.
    Peace

    I'm not getting any tone difference on this particular guitar by summing on the cable. No wimpifying. I would notice it, and wouldn't do it. That was one of the things I tested for, when I shorted my test cable. There was no tonal difference.

    Again, this is a guitar where it worked with the jack half way in.

    Tom, I suppose you could indeed use an adapter, but I hate adapters for live use. One more thing to go wrong. I just made myself a cable with TRS 1/4" and a mono 1/4", and it's working great, with no wimpiness.

    Re: ES-345 what cable do I use?

    I didn't make a video when I was shorting the stereo cable, so I could show you that the tone didn't change. You'll just have to trust me. However, I just plugged into my '53 Deluxe, with the tone and volume at 12:00, using the cable I just made, so you can see that there's no wimpifying going on.

    As I say in my comments, it's freezing in the studio, and my fingers are stiff. Sorry for the stiff playing and a couple flubbed notes.

    Re: ES-345 what cable do I use?

    Sounds pretty good to me JJ.
    Sounds like we need another shoot out.
    The stereo to mono cable vs using some sort of passive or active mixer.
    I've just been talking to a guy about making up a small active mixer.
    Here's what he had to say,
    " Many people don't know that simply combining signals can be problematic. Pedals like my passive mixer help with the use of summing resistors, but the active verion is definitely the best solution. It balances signals with mismatched impedance and eliminates crosstalk--or the level of one channel affecting the level of the other".
    I'm having him make a small active mixer with no switching.
    I'll let you know how it goes.

    Re: ES-345 what cable do I use?

    My fear of using a mixer is that I want the two pickups to affect each other in the middle position, like any other two PUP guitar would. There's that parasitic capacitance that happens, when you start turning one PUP down, and some LPF starts happening. It's part of the Gibson sound. I'm getting that in this configuration.

    Re: ES-345 what cable do I use?

    Yeah, interesting.
    The guy building my pedal asked if I wanted the two signals in or OOP.
    I told him to keep it OOP because that's the sound of these guitars, right?
    I'm willing to try everything possible before I change components in the guitar.
    For me, I need the freedom of a single channel/single input amp.

    Re: ES-345 what cable do I use?

    After years of fiddling around with the stereo setups with my ES345, I finally opted out by having it wired mono with the varitone still intact. Had it wired using the schem on the bottom right.

    It wasn't a difficult decision because my guitar suffered the wiring dry rot that plagued some guitars from this era. So, "originality" wasn't an issue for me, being a players grade instrument. Much happier with this setup.

    Re: ES-345 what cable do I use?

    My 67 walnut 345 has the pick ups wired out of phase but what I did find when I am in the middle switch position using a summing cable is that if I back off one of the volumes by 2 -3 on the knob the tone thickens right up.

    This was such a cool find as I can have that hollow BB King, Peter Green thing happening with both volumes equal and then back off one volume and I have a nice thick twin humbucker sound and best of all - no mods to the instrument.

    Continuing the age old 345 confusion questions. Here's another.

    I have an Historic ES-345 and the bridge pickup ONLY switch setting is low/thin. The guitar has a MONO output jack, (T/S). So I am assuming 1/4" MONO cable is the correct cable and the only choice. From what I can see without pulling it all out, the varitone electronics are all there.

    What I'm scratching my head over is why the bridge Pickup is much lower output only relative to middle position and neck pickup only. So middle position nice full sound in all varitone positions, Neck only is a nice full sound in all varitone positions, but why would the bridge pickup alone just be low/thin output.

    This doesn't make sense to me because all I have read says that when the middle position of 345's that are wired stereo, but summed in mono, are thin out of phase sound. But this 345 is definitely MONO output wired.

    Is there some sort of test I can do to see why this is?

    Is it possible that someone or Gibson just put a mono output jack in a stereo circuit? Ahh I don't know.

    The TR cover reads "Custom". Now I'm wondering maybe this is some sort of special request build.

    Just head scratching about this.

    Any Ideas on this would be appreciated.

    Did you check the bridge pickup?

    Re: ES-345 what cable do I use?

    Yeah see that's kinda sorta part of my question. Since all that is tucked deep inside there, How do I check something like that without removing any of that?

    Checking the bridge pickup through a 1/4" attached to the output jack is a correct Ohm measurement of a pickup on a 345?

    Re: ES-345 what cable do I use?

    I am only 5 years late, but I ended up removing the varitone circuit (weighs a ton) and installed one of Dr Vintage's pre-wired harnesses. He also fixed the one pickup for me and gave the other a once over (turns out one is a PAT number and one is a T-Top). The guitar is a feather weight (probably because of the extra routing they do on these and removing that big hunk of metal) and sounds incredible. My 345 is hardly a museum piece, so I did not feel bad altering it in this way.

    I have to say JT, this is weird. I think the first option is to indeed bridge check the pickup for trueness. Turn the varitone around to bypass and have the volume/tone on full (10). What readings do you get? I'll check my Historic 345 and post readings for the same later in the week. Mine sounds loud and full on all pickup settings, and yes, these should be all mono (Historics).

    Re: ES-345 what cable do I use?

    Hey guys thanks.

    Is Dr. Vintage still around? I can't find his website.

    With the volume on full and the Varitone on 1, and a 1/4" plugged into the jack, I get 8.55 on the bridge, 8.25 0n the neck.

    You know when I first got this guitar, the bridge pickup was very high almost touching the strings, so I suspect the previous owner was trying to "increase" the volume on that pickup. But, 8.55 leads me to believe the pickup is OK, but there's something else afoot.

    Re: ES-345 what cable do I use?

    Oh yeah!
    I found it!

    I peeked into the lower F-Hole and saw a bare wire loose and touching the three way switch. I reached in with a needle nose and wrapped it around where the rest of it was. I carefully went in with a drop of solder on that wrap.

    The bridge pickup now sounds like it should!

    Woo Hoo!

    Boy there sure are a lot of wires in there.

    Thanks guys for chiming in.

    So thinking about it, that loose ground wire was shorting the three 3-way switch.

    Sounds like a bad bridge pickup. It won't sound "out of phase" in the middle position if one pickup is much weaker.

    Re: ES-345 what cable do I use?

    It's good for now, hopefully it stays that way. If I find it intermittent, or goes back to the way it was, yeah that would be what that would be the best guess.

    Hopefully that loose ground wire wasn't supposed to go somewhere, because it was just hanging there against the switch.

    The only thing I could think of was that it is the bridge ground, but the bridge is dead quiet, no hum. oh well.

    Re: ES-345 what cable do I use?

    Good news! Yeah, with a correct pickup reading something else had to be afoot. Sorry I didn't quite get to read my own for you, but doesn't matter now!
