• Guys, we've spent considerable money converting the Les Paul Forum to this new XenForo platform, and we have ongoing monthly operating expenses. THE "DONATIONS" TAB IS NOW WORKING, AND WE WOULD APPRECIATE ANY DONATIONS YOU CAN MAKE TO KEEP THE LES PAUL FORUM GOING! Thank you!

Hey Tim C.! an idea...

I was thinking about that variable slope resistor idea of yours, and I thought what about putting a big blocking cap in front of the tone stack. Something like a .22 or something around that range.. That way it'll pass just about all of the AC and leave that slope pot to do it's thing???

I don't think that there *has* to be the DC offset there for the tone stack to work properly..

It could possibly be a "mid-shift/gain" knob.. Maybe something interesting to play with!

That's an interesting idea. I haven't tried it or heard of anyone else doing it either.

Maybe you'd better get a patent on it before someone else does. ;)

Cheers,
Tim C.

Hey it was your idea.. I just removed the DC..

I'd rather pass on dealing with all those patent lawyers and associated expenses!!

Hey Dave, that works great! I think Steve Ahola turned me onto that trick at AMPAGE. I've used that approach to find a good slope value for a particular stack, then measured the value and replaced the pot with a resistor. Likewise the mid-resistor in a Fender stack, replaced by a pot, measured sweet value, replaced pot with new resistor. Likewise for split plate loads to dial in good values.

Mad scientist stuff for the unquenchable tinkerer!

Hey, you know anybody interested in a 5A3 Deluxe from '51? Thinking of moving that one on. May move that Vobrolux I mentioned, too. Not collector grade stuff, just god old amps, ya know?

On my way to Key West to hang with the vocalist from my band in the 70s and early 80s. This guy is a hoot!
