Motion Sound KBR-3D Rotary Keyboard Amp

Regular price $499.00

This used KBR-3D is fully functional and in very good condition. 

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!
