I've been going over this in my mind for several weeks now, and I believe that I'm going to go ahead and switch my old Peavey preamp out for a Bartolini preamp. Since I'm limited to only three pot positions, I am thinking of going with the new HR-3.4, which is Volume/Volume, Mid, and Bass/Treble. However, here's the question. What if I wanted it set up this way. Volume/Blend, Mid (push pull Active/Passive), Bass/Treble. Is it possible to wire it that way? I'd like to have the ability to switch to passive if I have to, but the HR-3.4 doesn't have that option. The other option would be the HR-2.4, which is a Volume (push-pull), Mid (with frequency push-pull), and bass/treble. But then, that's only for a one pickup setup and I have two pickups. I don't think I'd be able to work a 4th pot in, but that would satisfy my problem. What would YOU do? By the way, I may switch the pickups out also, if my current pickups require it. I'm thinking they'll work though.
