  • preamp "tone control" adjustment?

    In my C-2 on the back of the preamp, there is an adjustment screw marked "tone control" what does that screw adjust and how? I was going to fiddle with it and see for myself but I'm getting smarter in my old age and fiddling less since i have screwed up so many things in the past doing just that. My C2 is hooked to a Hammond HR-40 and a Leslie 50C that has been converted to single channel use. It sounds good but super clean even when you floor it. I'd like it to maybe break up just a little, How do I get it to do that?

    The tone control is basically a treble adjustment. All the way clockwise is no tone effect or full bandwidth. Turning it counter clockwise will reduce the treble.</p>

      You might want to try adjusting the pot in the swell capacitor box for some preamp overdrive. Turning the pot counter-clockwise increases the gain. There's instructions on HammondWiki on how to properly set the level.

        This "pot" is not a potentiometer, it's a variable capacitor that adjusts the preamp overall feedback for stability. The factory setting is; </p>

        turn it all the way clockwise, then back it out 1 to 1 1/2 turns.</p>
