VINTAGE 1992 MESA BOOGIE 50 CALIBER PLUS AMP WITH MESA LEAD PEDAL SWITCH, EXTRA POWER TUBES and OWNERS MANUAL,NOT PICTURED HERE.  THIS AMP IS IN EXCELLENT CONDITION AND CAN BE BROKEN DOWN AND CARRIED IN AND OUT EASILY. AMP HAS 50 WATTS AND PLENTY OF HEADROOM FOR THOSE OUTSIDE GIGS. MASTER VOLUME TONES DOWN THINGS FOR THOSE NOT SO HEAVY NEEDS INSIDE. I HAVE OWNED THIS AMP SINCE 1992 AND HAVE BEEN VERY PLEASED WITH ITS SERVICE. IT IS JUST TIME TO LIGHTEN UP AND MOVE INTO THE RETIREMENT MODE. YOU CAN SEE AN AMP DEMO FOR THE 50 CAL PLUS ON YOU TUBE. JUST TYPE IN " MESA BOOGIE CALIBER 50 PLUS SOUND TEST ".  AMP SOUNDS GREAT!
