Guitarists are familiar with the tube amp stacks that sound amazing when turned up loud on a big stage, and with combo amps that are a perfect fit for smaller venues and rehearsal. THR ignored the convention that a practice amp should simply be a smaller version of a larger amp, creating a new “third amp” category designed around what players need when they’re playing at home.

All THR-II models feature Bluetooth connectivity for audio playback, the “THR Remote” mobile editor app, and third-party footswitch support.
