I haven't swapped out the pre on my MM. I dig the bass after a year and a half with it, but I'm not totally sold on it. I'm an Ibanez fan in general, though, and came across a Butterscotch Trans 1200 that I like. It's at GC, which of course means it needs a setup, a battery, and new strings. It also means that I can't really compare it to my MM just sitting in the store. I'm fairly handy with a semi parametric mid, so the tone controls will be better for me, I think. Thought I'd ask for thoughts on this.
