Another GCB-95 Wah Mod Question?!

[Bill Gnarlson]

I know there's loads and loads of threads and material to read about modding the old dunlop crybaby but, as far as I can tell, I haven't seen this asked:

So I'm doing the typical to mine: TBP, some vocal mods. I'm also doing stinkfoots "tri-wah" mod, using a SPDT 3 terminal switch, with three caps connected with one leg, their other legs merged to 1 lead to the spot on the PCB.

My question: Could anyone run down the steps needed to perform the LED mod, with a twist; I want three LEDs of different colors to that correspond to the three positions on the SPDT on/off/on that's switching between the three caps. What do?

You could manage it with 2 LEDs (or a bi-colour one)..
OFF position (stock cap) -> No LED lit..
DPDT (ON - OFF - ON) switch..



P.S.
In case you experience issues with different colour LEDs brightness, you can delete the common CLR and place individual resistors in series with SW middle lug..
(soldered onto switch or between respective lug and LED anode or between LED cathode and GND..)
