GMaqOrgan player can't make the gig? No MIDI keyboard? No problem! MOD Duo to the rescue with the setBfree 'Whirl' speaker Leslie emulation. To fake organ sounds roll back the tone on your rhythm pickup and play fingerstyle with lots of high drone notes. Don't forget if you do have a MIDI keyboard you can emulate the real Hammond B3 thing with the setBfree organ generator, this pedalboard is for faking it with a guitar.
