Ok, so I'm torn between two preamps. I really like the Aguilar DB-680 and then again I also like the Alembic F2-B. Right now my main bass is a Fender American Jazz with a nickel nut and Dimarzio Ultra Jazz pickups. I also play a custom 5-string with a Music Man style pickup. My cabinets are Acmes and my power amp is a Stewart World 2.1. Here is an example of the music I play <a href="http://csunix1.lvc.edu/~mflury/Fivestar%20Mortal.mp3">Click Here!</a> I had to cut the quality down for all you people who might have dial-up out there, but it's probably the best representation. I'd like to sorta retain this tone but ameliorate it if I could.
