The culmination of a 4-year joint project between Yorkville/Traynor and the Federal government, this series of Traynor amps from the mid-70’s took “Innovative Technology” funding to create some great Made-in-Canada solid-state amps. Designed headed by 4 of Traynor’s engineers, these amps were dubbed the Group Series.
The Group One head is a 50-watt head using MOSFET solid state devices, and active tone controls (very uncommon even to this day). The active-EQ circuit made semi-parametric controls possible. The Mid controls, as well as a range selector, shift the midpoint of the control knob – and can create a cool phase-shifting effect if a volume type pedal is connected as a footswitch (not included).
The rugged Aluminum chassis was less bulky than other designs of the time.
The amp has Hi and Lo inputs, 2 channels, onboard reverb, and tremolo.
