Killer tube tone and power with endless flexibility at home and on stage.

The Acoustic GT50H 50 Watt all-tube guitar amplifier head is for the musician who demands more from an amp. The GT50H offers a variety of tube-driven tones, from a warm, mellow clean to classic crunch to an insane overdrive ” and everything in-between. Featuring both a Pentode and Triode mode, along with a half-power switch, the GT50H provides a wide range of output options from 12 to 50 watts while keeping its rich tone intact.

Tube complements include two 6L6GC power tubes for a balanced and versatile tone. The preamp consists of two tried-and-true 12AX7WB's and two ECC83S's for a smooth tone.

With multiple speaker outputs, the GT50H can power 4, 8 or 16 Ohm load cabinets and boasts an Accutronics spring reverb and an effects loop. The included 4-button footswitch gives you total control on stage with Channel Switching, High Gain on/off, Reverb on/off and Lead Boost on/off.
