SURPRISE SOUND LAB - Key Persons
The Rock Block provides 7X clean power and 2X max power compared to the ZVex Nano Head. Unlike other micro-power amps, the Rock Block has usable clean headroom. It also has much more flexibility and control. Most importantly, it just sounds better. The Rock Block has Gain, Volume and Tone knobs and a separate Volume knob for the output that drives another amp when the Rock Block is used as a distortion pedal. It also has 3-way Boost and Bass switches, a Power switch, and a Bypass stompswitch.
