The Wah pedal
I had to modify my wah pedal, first was the pot, it became noisy, it had to be replaced, I used a Dunlop one, but within weeks it was the same. I found a replacement, its been in there for a few years now, problem solved.
Then, I was out playing one day, and it occurred to me, why doesn't it have an L.E.D. like other pedal's? I was also reading up on true bypass switching. So a little trip to ebay and a new switch and some L.E.D's were on the way, all that was needed was to drill a 5mm hole for the L.E.D. And a some clever wiring. Job done!
