I just purchased this amp a couple months ago. I've owned a couple B-1500's previously and always found them to be rock solid, dependable, great-sounding, and LOUD. But I always had a hard time getting the amp EQ'ed to my liking -- until I read Tom Bowlus' review in Bass Gear Magazine. Once I understood the EQ frequencies better, I was happier than ever with the amp! Once thing that Tom mentioned in his review was the knobs; the black lines on chrome knobs make it hard to see your EQ settings. I've replaced the chrome knobs with plastic Mesa-Boogie style plastic knobs that improve visibility and reduce weight. But I still have the original knobs and will include them or swap them out if you like. Also, the input jack had worked itself loose. It was a simple fix, but while I had the top off, I tapped all of the screw holes for 6-32 threads and replaced the screws with stainless steel socket head screws so that you never have to worry about stripping them if you ever have to service the amp. I also replaced the chassis screws on the front with stainless, just to add back some "bling" after I removed the chrome knobs. The amp is in great shape, with only some minor wear around the rackmounting screw holes, and a couple scratches on the bottom. $400 shipped (in the 48 states), and it's yours! PayPal accepted, trades for other bass heads (or a power amp) considered, although a straight sale is preferred.
