The GT120 is a reissue of the original 70s amp. Unmistakable Green Matamp organic sound at incredible sound pressure levels or classic Matamp warm clean.

The preamp is the original circuit including the four position drive switch, bass boost and presence/boost circuit incorporating the inductor.

The key to this amp is its clean tone. The preamp has origins going back to the days of Orange Matamp when Peter Green described the tone he wanted to Tony and Mat as “sweet….but not like treacle…like honey.” Coupled with four EL34s the warm sweet clean tone is a perfect match for fuzz.

The power amp has been slightly updated to feature individual bias adjustment per valve. This makes matched sets a thing of the past and enables the user to replace a single valve while still maintaining optimum performance.

The big difference in this reissue is that the amp is now hand wired on turret tracks, our hybrid PCB turret construction method that we have been using throughout this millennium. Greatly improving reliability and serviceability over previous versions, including the original amps from the 1970s. We have searched the country to find a transformer company still capable of making transformers that live up to the quality and reliability of the old units.

The GT120 can drive multiple cabs from the 4, 8 & 16 ohm speaker outputs. The amp has been updated to allow multiple cabs to be connected direct from the head without daisy chaining.

Also available in Green for no extra cost!
