The classic Leslie speaker, made to Don Leslie's original recipe, as it has been since 1941. This two-speed speaker uses a traditional tube amplifier with a speaker in the horn and a special 15" woofer for bass.

Connections are made via the 11-pin plug found on all modern Hammonds, and some clones. For older Hammond models, adapter kits are available. This optional interface panel is available with a ¼"" cord input and a jack for a footswitch; eliminating the need for a bulky cable and a "preamp box".
