The Gibson Titan 135 is one of the most powerful amplifiers Gibson ever built, pushing approximately 135 watts through eight 6L6 output tubes. Designed for the largest professional stage and auditorium use, it was among the most powerful guitar amplifiers available anywhere in the mid-1960s. Two channels and comprehensive controls provide tonal flexibility at this extreme power level. The Titan 135 is an extremely rare and historically significant American amplifier — a testament to Gibson's ambitions in the high-end professional market.
