I bought a Bartolini 3-band preamp for my Dean, but seem to like the sound of the original 2-band preamp...which also sounds a bit hotter and louder than the bart. So I put the original 2-band back into the Dean and now I have a pretty sweet Bart preamp sitting in a box. I also have a "cheap" (read: "inexpensive") 6-string fretless bass from Rondo, which has an OK preamp (Artec) but I feel like it's missing something, and I'd like it to be louder (switching between the Dean with Bart preamp to the fretless, I'd have to raise the amp master volume about 1.5 clicks to match the output of the 2 basses). My experience with bart preamps and fretless basses is very positive, lots of growl and oohmf...but I'm wondering if I should even dare combine the 2. I would have to do a bit of pot-hole enlarging to fit the preamp in there, and maybe even drill an extra hole depending on whether I use the 4 pots the preamp comes with plus a pickup selector (total 5 holes), or 3 standard plus one stacked pot (total 4 holes). What would you do...say "F*** it" and start drilling, or don't bother (the preamp costs as much as the bass)?
