A 2-way Mid Shift and 3-way Bright switch allow you to fine-tune the tonal character of each channel to suit your playing style.

The rear panel offers an impressive array of features: a speaker-emulated recording output with two voicing filters, a headphone out , unfiltered line outs , an effects loop , a power soak , and a speaker on/off switch for silent recording or practicing with headphones.
