Studio-Grade Power for the Stage

The GTR-100 is a 2-channel class A/B power amp designed for modern guitarists who rely on guitar modelers like AxeFX or Quad Cortex to shape their sound. Its solid-state design ensures that tones ring true, and with up to 140 watts of power per side—or 245w in bridged mono mode—it can make ears ring as well. Switchable Line/Instrument inputs let guitarists connect either a modeler or stompboxes directly with perfectly matched impedance.

The clean amplification GTR-100 provides won’t add unwanted noise or distortion to carefully-crafted tones, even when pushed to earsplitting volumes, and comes with none of the maintenance hassle or cumbersome weight of tube amplifiers.

The channels can even be used as two independent amps if there are two guitarists in a band, making the GTR-100 a perfect solution for an all-in-one road rack.

The Features You Need; the Power You Want

GTR-100s stereo ins and outs let guitarists bring stereo modulation and delay effects to the live arena, while its switchable 4-band EQ grants nuanced tone-shaping to suit whatever room is being played in. The XLR Thru outputs allow outputs to be split to a mixing desk or recording device for reinforcement or recording of a performance—no cabinet mic required. A switchable per-channel analog cabinet simulation emulates the sound of a miked 4x12 cabinet, and sends this processed signal to the XLR outs.

Output levels can be perfectly balanced with independent level controls and 14-stage input/output metering.

Road-Ready Reliability

GTR-100 is ruggedly built for the road, while weighing far less than an average tube amp. Its sturdy metal handles extend well past the extrusion of the control knobs, ensuring that they won’t get damaged in the event the amp takes a tumble. The protect indicator lights to warn of any conditions that could lead to damage to the amp or connected speakers, while the whisper-quiet cooling fan ensures overheating will never be a problem. Its rear-mounted rack rails make cable management a breeze when racked.
