Thank you for the advice gentlemen, MUCH apprectiated! I really like this site because I am just learning this electronics thing and really enjoy it.

But, I guess I'll stick to modding pedals ... for now. I play Jazz guitar but do Blues to be able to play with other musicians in the area since where I live it appears there is only Blues and Rock. LOL!

The clean channel is why I purchased the amp (it was a steal at $300 US! Sitting unused, like new, in a funeral parlor for the past 15 or so years) but wanted to modify it so that I would be able to play the two genres without messing with pedals.

Maybe I'll try to build an amp how I like it. I know how about an overdrive/distortion pedal with tubes ... hmm. Any ideas.

P.S. Destroid, like Phatt said. It's fuzzy and REALLY muddies up the sound. Not usefull at all for other than one note leads (aka whimpy/weak guitar playing) and mucks up chords.

Thanks for the insight. I appreciate any help. Reconnecting the leads seems a bit simplified. But as far as some "food for thought" for me. Would you guys make some recommendations as to where to start?

Newbe here,

I would like to change the distortion on my JC 120.

What I what I would like to do is to replace the circuitry of the integral distortion with that from a BOSS Blues Driver that I have and for the distortion controls on the amp to operate the effect as though the Driver were the distortion as installed by Roland - all else the same.

Has anyone done this? What is involved? Would I be able to get the same sound as the Blues Driver by just modifying the current distortion???
