Similar to the B-2, but with the added harmonic percussion circuit. Model B style cabinet with variable vibrato (V1, V2, V3, C1, C2, C3) The first organ produced in the deeper Model B cabinet, to accommodate the chorus generator Model B-C style organ with built-in player organ mechanism (possibly Duo-Art), custom built by Aeolian-Skinner. Ī B-3 / C-3's internals in an integrated package with power amp and speakers Two 61-note manuals, 25-note pedalboard, 2 x 9 drawbars per manual, 2 pedal drawbars, 9 presets per manual, a tremolo effect generator ('tremulant'). As the magnetism varies, that induces an alternating current (AC) in the coil, which becomes one of the frequencies used in harmonic synthesis. As the teeth of the tonewheel pass by, the strength of the magnetism changesâwhen the tip of a tooth is closest to the tip of the magnet, the magnetism is strongest. Each tonewheel assembly creates tones with low harmonic content, close to a sine wave. Tonewheel organs generate sound by mechanical toothed wheels, that rotate in front of electromagnetic pickups.
