1980 Firstman BS-999 Bass Synthesizer Vintage Analog Foot Pedal Keyboard
Tonally, this synth can range from short, percussive thumps to full-on, beefy analog richness. The BS-999 features a straight-forward, no-frills design and control configuration: the monophonic, single-trigger synth features Octave (Low and High), Effect (Hold, Sustain, and Expand), and Attack (Percussion and Mute) footswitch control sections, plus knobs for Tuning, Sustain, Expand, Tone, and Volume. The Expand button delivers an immediate dose of Moog-style single oscillator synth tonality, and dialing the corresponding knob while the Expand mode is engaged enables VCF sweeps. Similarly, the Sustain button dictates whether the sustain effect is on or off, with the length dictated by the corresponding knob, and the Tuning knob can alter the note up to a half-step in either direction.
This is a well-kept unit, with sparingly little playwear. The original knobs are present, and all of the pedals are very responsive.
