So I had this idea that I could put the Tiger Eye sweep mid preamp (actually a USA Millenium preamp... even says so on the circuit board) in my standard Cirrus... So I'm currently awaiting the preamp and a few knobs. I've already spoken to a tech at Peavey and he advises that I'll probably have to thin the body for the mid control so the pot sticks thru far enough to get the knobs on properly. He also says I'll prolly have to make the hole larger as well. We'll see. I really don't wanna' start cutting wood out... especially if it means it's an irreversible mod. Generally don't like those. Clearly the first thing to do is see if I can find a concentric pot that fits as is. Dunno if there is such a beast, but I'll look if need be. Anyway, I'll post here after I have a chance to dig into it a bit... prolly next week or later. Wish me luck!
