For anyone looking for an Aguilar DB728... it's not something that pops up every day. I already have one and a Demeter VTHF-300M, so I'm not in the market. I wouldn't mind a sweet deal on the Fender TBP-1 preamp that comes with it though.
It came up during my continuing search for the Aguilar DB680. I'd appreciate a lead on one of those if anyone knows of one.

If I wasn't so terribly pleased with my amp situation right now, I'd buy that just to have the DB728. That amp spent a lot of time on my short list of "amps I wish I owned".
The DB680 is a fun thing. Good luck with your search. I owned one ~20 years ago and eventually we parted ways when I discovered how much more fun a Mesa 400+ through two Mesa Diesel 2x15 cabs can be. :D
