The Tigermate and the Tiger are identical except for the rhythm unit, which adorns the only the Tigermate. http://www.combo-organ.com
The bass section comprises the first 20 keys (C-G) on the left, but there are no markings to indicate that. The "drawbars" are really just on/off switches - they only pull out about 3/4". The vibrato on the one I played was very slow - it must have needed adjustment. There's no line-out jack, only a headphone jack, but if you plug that into an amp it works pretty well.
- "Drawbars": Mello, Reed, Brass, Flute, Bass Chorus, Vibrato
- Knobs: On/Off Volume, Bass Volume, Tone
