For sale. Mesa Boogie Dual Caliber 50 watt head in great condition. This thing is incredibly loud to be only 50 watts. This amp is incredibly flexible with great cleans and amazing crunch. $800.00. This posting is for the head just. I'll throw in the Vader 2x12 cabinet (Eminence speakers and coated in Rhino-lining) for an additional $200.00. Money only. No trades.
