Just like a B3, only you can get the 32' and 16' pedal tones using the lower two sliders on the bottom keyboard! Smaller cabinet than a B3, but way bassier. The guy from the shop loved it and it kind of killed him to deliver it for use without a Leslie... he said it kills through a Leslie. This is the shop that did organs for phish and the Allmans. Percussion upgrade, recap of the tube amp, retube oft the organ and amp. I'm stoked.
