As with the Alembic F1-X thread starter below, I find that my Ampeg SVP-Pro preamp is not nearly flat with all the controls halfway up. However, the Ampeg, to my ears, has the opposite of the Alembic's issue -- the Ampeg is TOO middy, and not transparent ENOUGH. I recently switched from SWR to the Ampeg, and am having a lot of trouble getting the clarity to which I'm accustomed for playing fretted basses. OTOH, the midrangey-ness makes my fretless G&L L-2000 go "WHaaaaaaaaahhhh" like no other amp I've ever tried. . . . BTW, I play thru a Bag End S15D cab, if that's a factor. . . . any advice on getting the SWR-like tone out of the Ampeg when I want it?
