Re: How easy is it to install blend knobs in OD pedals...?
I'm just brainstorming as I type here, what if you made an adder out of an opamp and used a dual gang linear pot to control the gain of each input? One input would be the signal after the OD circuit and one would be a tap from before the clipping stage? I don't know if that type of pot would give you the smooth, constant gain you'd need, what type of pots do they use for faders in mixing boards, are they dual gang, log/reverse log taper?
