I have a Carvin BX-500 in great condition available. This amp is pretty killer, and my friend who plays upright loves it for his needs as well as BG work. Built in comp, multiple eq's, 2 ohm capabilities, ect.
This unit is in good cosmetic condition, with a couple of scratches, mostly on the bottom. It's fully functional except for the D.I. out. The D.I. out has a horrible buzz/distortion which makes this feature of the amp unusable. Other than this one issue, this is a great head. Comes with the Rack adapter, so you can drop it in a standard width rack with no issues.
The stock tube has been replaced with a Groove Tubes 12-ax7. I had it lying around and liked the character it gave the amp, so the two are now traveling companions.
Prefer sale right now, but will take trade offers, mostly looking for:
Dingwall compatible strings
3leaf envelope filters
Nordstrand dual coil pickups in EMG 40 shells.
ACG filter preamps
