AMAZING!!!
AFTER USING TUBE HEADS FOR YEARS AND UNHAPPY WITH THE QUALITY AND PRICING OF MODELING/PROFILING HEADS. I SPENT A FEW HOURS WITH A BOSS REP AT SWEETWATER'S 2019 GEARFEST. I HELD OFF UNTIL THE MKII VERSION WAS RELEASED AND I ORDERED 2 OF THEM TO RUN A TRUE STEREO RIG. I CAN RECREATE THE TONE OF MY ORIGINAL PEAVEY "EVH" 5150 HEADS WITH EASE. MY RIG WENT FROM OVER 200 LBS. DOWN TO LESS THAN 100 LBS. BEING ABLE TO LOAD MY OWN TONES USING AWESOME BOSS EFFECTS, CHOOSING WHERE THESE EFFECTS FALL IN THE SIGNAL CHAIN AND 3 DIFFERENT POWER AMP VOICINGS. THESE HEADS OFFERS JUST WHAT I NEED, I AM USING THEM AT A PRO LEVEL WITH VARIOUS 4X12 CABINETS WHICH INCLUDE, MARSHALL, PEAVEY 5150 AND MESA.
