There are a few iconic valve guitar amps that we at Mozztronics adore. Apart from the British 800 series amps, and the AC30, the other is an American 59 bass amp loved by guitarists for the breakup when the amp is cranked. This amp is very similar to the Tonemaster made by the same company, and we have used a combination of these two amps as the basis for our solid state foot-switchable pedal, which we have named the "ToneMeister". This pedal is not a dirt pedal as such, it's our emulation of these classic amps. To do full justice to the original amp, and to get the maximum in tone versatility we included the full 3 knob tone stack in this pedal. A single tone control wasn't going to cut it with this pedal. GAIN controls the amount of gain from the first stage, BASS, MID and TREBLE are the classic 3 knob tone stack as found in the original amp. VOLUME adjusts the overall volume out of the pedal. As with the amplifier this pedal replicates, at lower gain settings, you get the sparkle these amps are known and loved for. Turn the gain up for added rawkus-ness. Davey Lane commented about this pedal Just had a chance to try out these new pedals (DL-30 Driveline & TM1 Tonemeister). They're both amazing and the best things youÕve done yet. Super creamy breakup on both. Thanks Davey, turn them up loud !
