This Garnet BTO is one of the rarest amps in Electrical Audio’s collection. The 120-watt amp is monstrously loud—and so powerful that they’ve been known to melt the voice coils of cabinet speakers—and sports a built in tube-driven fuzz and tremolo. Interestingly, the BTO moniker stands for “Big Time Operator,” rather than “Bachman Turner Overdrive,” which is an old wives’ tale amongst gear hounds.
