I'm looking for a bass preamp to use with my Crest FA901 poweramp. I've been offered to trade my Trace AH250SM head for the Ampeg preamp mentioned above, = $100. Who's going to write me a response coarsely thrashing me for doing it? Am I SO WRONG??? I've got a JBL 2226H in an EAW V-125B cab, and my sound is pretty dang promising at this point. I'm not sure a preamp is the most critical link in my chain. Fender Jazz w/ EMG Vintage J's along with this other stuff I've mentioned. Any advice? -Stewbone.
