Independent gain and master knobs and a switchable FX Loop are standard appointments on modern triplechannel amps. But that’s not nearly enough for a real TubeMeister. So Mr. Hughes and Mr. Kettner built in a MIDI system to access the channels, FX loop and onboard reverb. It can even select the power stages of the integrated power soak (36, 18, and 5 watts, 1 watt and Speaker Off)!
