This unassuming looking amp delivers huge tube-like tones in the form of 15 different guitar amp models, 3 bass amp models, 3 mic models for shaping your amplified acoustic guitar tones, and flat settings for keyboards and whatever else you want to throw at it. This small marvel also boasts a slew of effects, reverbs and delays, all of which benefit from the THR's mind-bendingly huge extended stereo field output. The THR10II also supports Bluetooth for audio playback and easy tone editing via the THR app.
