The TubeMeister 36 features three channels with dedicated GAIN and MASTER controls. Think of GAIN and MASTER as the yin and yang of sound-shaping for all three channels. The best way to probe the channels’ many sonic possibilities is to experiment. We recommend that you set the POWER SOAK to five-watt mode and all knobs to the 12 o’clock position. Then adjust GAIN/MASTER settings at will to get a taste of the very different flavors of preamp and power tube distortion. The further you back off the MASTER knob, the drier the amp’s sound. The further you turn the knob up, the juicier the power tube distortion. All of TubeMeister 36’s channels are very responsive to the input signal. You can conjure a remarkably diverse range of sounds simply by varying your choice of pickup and adjusting the guitar’s volume knob.
