Graphic 120 Master Volume

[spoonman]

I own a mid-90s Graphic 120 re-issue head.It gives me great clean tone and distortion with a pedal. But I'd be interested if anyone has specs for a modification to add a master volume, as in the Graphic 120 Overdrive.

...you should look on Geert Jacobs' site. It is relatively simple if you are the least bit electronically inclined. If you're not though, don't mess with it, let someone who knows what they're doing mess up your amp. If you break it, you're screwed, if they break it, they have to fix it for you.
