I've decided to sell my Aguilar DB 680 tube pre. I'm the original owner since 2001. Initially, I used it for select club dates, but then "retired" it from live gigs for use strictly on studio sessions. However, I haven't used it at all this last year...so it's time for it to go. Although I bought it as the front end to my electric bass rig, it sounds quite nice with DB -- especially considering the amount of EQ available. http://www.aguilaramp.com/products_preamps_db680.htm I've got the manual and footswitch (never used). I'm asking $800 firm plus shipping. I don't do online payment transactions so I'd need a certified or USPS check. Email me at email@example.com if interested.
