Modify your own Guitar FX Pedals

My Friend Brian Wampler was kind enough to send me these cool videos on how to modify some of your Guitar FX Pedals. I'm very proud to be bringing you articles like this because it opens doors to areas I thought were off limits to non electricians and only for the pro guitar techs. I hope this little clinic will give you the courage to not throw your old pedals away and start supercharging them just like the pros do! ENJOY!- Scott 

Who is Brian Wampler?

I've been playing guitar since I was 7. I'm 31 now. I distinctly remember how it happened...my brother was in a high school rock band, and they were practicing at our house one day. I was enamored by the guitarist...He had a Gibson Flying V, and they kept practicing the same song over and over..."don't tell me you love me" my Night Ranger. Sad but true! That is the point that started it all!

My Grandparents were even in a band in their youth, and even received quite a bit of radio play in their day. So I guess in one way or another, I was bitten by the music bug genetically.

I always have been kind of a 'gear geek'...always trying different guitars/amps/effects to achieve certain sounds. It wasn't until 2001 or so when Paul Weller (FiremanFx) modified a pedal for me, and I was amazed at how much better it sounded. I immediately opened it up, wondering what he had done to make it sound so much better...

That is what sparked my interest in the Effects modification world...I had always been good with my hands and a quick learner, so I dove in head first and read, and read, and read some more. Then I bought several different effects and tested other's ideas, as well as my own. I was astonished at how one capacitor or resistor could make a pedal have much more bass/mids/treble/distortion/etc.

I actually holed myself up in my garage for about a month, replacing components in key areas, one at a time, and recorded the results on the first 'mod sheets'. These were just notes for myself to remember what I did, and what the change effected. I did this one at a time, for every pedal I could get my hands on...each time recording the results, and recording the before and after tones from the pedal through the same setup.

I modified a few for the folks at Harmony-central effects forum, and the response was crazy...almost immediately I saw there was a demand for a service modifying pedals, even though a few were already doing it. Word of mouth grew quickly...

Within about a year I was literally working 18 hour days, modifying pedals like crazy...even famous musicians were calling me asking me if it would 'be alright' for them to send me their pedals...some even invited me to come with them into the recording studio, so they could get the exact sound they were wanting...sort of an audio consultant...what an exciting time!! The good thing is it hasn't slowed down -- in fact, its picked up quite a bit!!

Nowadays I can turn on many radio stations and hear my pedals -- in fact my pedals are being played on most of the country songs you hear on country radio nowadays!
