50 Watt Tube Amp Head

Acoustic® is proud to introduce the new GT50H 50 Watt Tube Amp Head, our all-tube guitar amplifier head.

For the musician who demands more, 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, musical, and versatile tone. The preamp consists of two tried-and-true 12AX7WB's and two ECC83S's for smooth tone — and to help boost clarity by minimizing microphonics.

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.

Match it with the Acoustic® G412AC cabinet loaded with Celestion® speakers and you're ready to rock any venue! With 240 Watts of power handling, convenient mono and stereo modes, metal handles and heavy-duty casters for easy transport, the G412AC allows you to command any stage!
