The Apollo VIIb is a medium-gain overdrive and preamp derived from the preamp section of the Voyager tremolo. It delivers dynamic overdrive tones with rich harmonic content and strong touch sensitivity. A three-position clipping switch offers VOY, ALT, and Boost modes for different response and breakup characteristics. The Gain, Tone, and Level controls provide flexible shaping from clean boost to saturated drive. The circuit is fully analog and true bypass. The Apollo VIIb is built in Portland, Oregon by Spaceman Effects.
