I have been trying to re-purchase an Alembic F1-x preamp for a month with no luck. (I used to own one but had to sell to fund a move.) I am getting ready to settle for a second choice, but I don't know what that would be. Any suggestions? I am running Fender MIA J-bass powered with a Qsc Plx1804. I am looking for a punchy, fat tone.
