has anyone installed an LED in an effect pedal??

[hottub]

just curious to see if anyone has done this to a pedal. I have a pedal that I would like to do it to and I'm looking to find out some info about it.

Really easy but only if it is in a pedal with an old style mechanical switch! All you need is your choice of led and a resistor in series to drop the voltage down suitably.

Most leds run at around 2 volts so look at the operating current in the spec of the led of your choice. You then use RESISTANCE = VOLTS/AMPS to work out the resistance of the led.

To find the value of the series resistance (assuming a 9 volt pedal) you want the series resistor to be 7/9 of the total resistance. So in a nutshell it must be 7/2 or 3.5 times the resistance of the led.

I would replace any mechanical footswitch with a 3PDT footswitch from Stewmac.

If you can't follow this let me know exactly what pedal you want to fit it to and I'll try to guide you through.

This what you looking for?

I haven't built it (but have been meaning to).THIS should do the trick.

I've used the Millenium Bypass circuit on a load of things. Works great and only needs the standard DTDP switch.

Yelly,

I have a DOD 250 OD/Preamp reissue. It has the mechanical switch with 3 leads coming off of it. I'm not really worried about true-bypass at this point as the pedal is pretty transparent already. Can I wire the LED to the existing switch?? Can you walk me thru the wiring process using the resistor, etc. ??

Hottub, you should receive a email with most of what you need. Let me know if you get it. It is about 100kb as there are 3 attachments so don't worry if it takes a while to download. Let me know if you have any more queries.

Thanks!

Yelly, I recv'd the email. Thanks man! I really appreciate it!
