The Triple Crown TC-50 Combo Amp from Mesa/Boogie captures the essence of rock combined with the iconic Dual Rectifier and a bold set of circuits. From bubbly, sparkling clean sounds, rarely heard in this type of amp, and an amazingly tight and aggressive wall of rock crunch, to one of the most vocal, harmonically rich and gain-laden high-gain channels ever, the Triple Crown is aimed at rock’s high-gain throne. The handy Bias Switch allows the stock complement of EL34s to be swapped for the fatter, rounder 6L6. For those who want a warmer response and a more easily attainable power clip, 6V6s can also be used in the EL34 setting with a direct swap over, creating a “half-power” scenario that exudes a bubbly, vintage voice with a creamier top end.
