I have a geddy lee jazz bass which has a seperate volume control for each pickup. Now dont get me wrong i love my bass, but i hate having two seperate volume knobs. My band's guitarist always cranks it for "Roadhouse Blues" so then i have to turn up as well, then turn down again. I would prefer to do so on my bass rather than amp. i always have both pickup vol. at ten as i like the sound of both pickups maxed. so the question is, w/o spend alot of money, or any money, can i solder one volume knob to work with both pickups w/o doing any damage?
