As a result some of the other effects aren't available when using this effect. Rotary Speaker can have it's speed changed via footswitch like a real Leslie. Early Ref 1, 2, & 3 are gated reverb effects used mostly for drums & percussion. Effects 26 thru 33 are Dual Mono effects. So it's possible to have 4 Mono effects available at once or 1 Stereo and 2 Mono. |
