Vox Q-Series Bass 100 preset

Close · 70/100 confidence. Most values readable. Minor gaps filled by inference from similar circuits.

The Q-Series Bass 100 is a 1987 solid-state Vox bass amp. Hi and Lo inputs feed an op-amp preamp with a switchable compressor built around an NE571 compander, with Sustain and Attack controls. A Bass, Middle and Treble stage follows, then a five-band graphic equaliser that can be switched in or out, and an output buffer feeding the 100-watt power amp.
