MOTION SOUND KBR-3D
Awesome Rotary Speaker Keyboard Amp
Need swirlicious organ sounds that only a real mechanical rotary speaker system can provide? Motion Sound has an excellent suggestion for you: the Motion Sound KBR-3D. The KBR-3D sports two stereo channels: Hi-Fidelity (for synths, pianos, etc.) and Rotary (for organ). A 12AX7 in the preamp stage lets you dial in the preferred amount of tube grit. You get tons of control over your sound, including a 3D spatial expander that greatly expands your stereo image, and an included footswitch that lets you control rotor speed. Factor in its curb weight of only 70 pounds, and the Motion Sound KBR-3D makes an ideal gigging keyboard amp.

Engineered to sound amazing
The KBR-3D sounds fantastic, and it gives you a ton of control over your sound. It sports a 12AX7 in its preamp stage, letting you dial between squeaky-clean and crunchy tube overdrive - and all points in between. You also get a contour control (4-7khz) that lets you emulate the frequency response of vintage rotary speakers. The Post Gain pot controls the volume of the rotary horns and low-rotor simulator. The Stereo simulator is mixed into the Hi-Fidelity channels. Two microphones are built in with level controls mixed into the XLR line outputs. It all adds up to one stunning keyboard amp!
