SN A 2 via this auction
"Crumar OMB-2, crumar one man band. Extremely cool and vintage.
It produces a basic analog synth bass sound but has an external rhythm box.On the pedal board are 13 bass pedals and a volume pedal with 2 switches. One switch is used to have the chords switched to minor, the other to 5ths. Also 3 push buttons for start/stop, manual/auto bass and sustain mode. The rhythms are basic and only have a few controls for volume. You can control chords, rhythm and bass volume as well the overal volume. Some switches to enable or disable chords etc. are on it too.
Hasn’t been serviced since the 1970s. sometimes need to hold bass notes down for couple seconds before note is proper. Rhythm volume only working in one position for drums, all other volume knobs working fine."
