Mesa Big Block 750 bass head in Mesa Vintage style head case. The head has always been in the case and is in perfect condition, built in tube overdrive, foot-switch included. VERY loud. New tubes throughout (Preamp and overdrive section, 4 total) Mesa Hollywood replaced the tubes and inspected the entire amp. NO issues. Serial # 88 I’ve got all the paperwork. If you are not familiar with this amp go to Mesa’s site and check it out. $900. with the case included is a slamming deal. Thanx, Manny. Los Angeles area only.
