Killer head! I've had this bad boy for a while and it has given me 0 problems. Low mileage as well. Only seen a few gigs here and there.
From the Carvin Website:
"The B800 employs a mono block design and offers the same rich tone generated from discrete Class A preamps. The power amp features an Active or Passive front panel input gain switch, along with Preamp Drive and Master volume controls. Additional front panel controls include Sub Bass, Bass, Low Mid, Mid, Hi Mid, and Treble.
The B800 incorporates a rear panel Direct Out on an XLR (balanced) connector with level control—enabling the unit to patch directly into PA systems or recording equipment. Bassists will also appreciate the effects loop built into the B800 with its front panel switch. And for making certain that they’re in tune with the rest of the band, the B800 includes a Tuner output jack that is independent of the Mute switch. To protect the system’s electronics, the B800 is encased in a rugged housing that is covered with a Duratex scratch resistant, weatherproof, polyurethane coating. Carry handles are mounted on the amp head’s sides.
