The Q-Series Lead 100 is a 1987 solid-state Vox amp. Inputs A, B and A+B feed op-amp Clean and Dirty channels, each with its own Gain and Boost, switched by footswitch with indicator LEDs. They share a Bass, Middle and Treble stack and a Volume, followed by a five-band graphic equaliser with its own level and on/off switch, and a reverb with a footswitchable Boost/Reverb pedal input, before the power amp.
