The first Dedicated Keyboard amplifier for Keyboard Players
Designed from the ground up as a state of the art Keyboard amp, the KBR-3D features 200 watts of power and a tube pre-amped rotating horn. You no longer have to settle for a sterile amp designed as a monitor while your guitar playin’ buddy run’s his own unique tower of power designed specifically for his use. This Full-featured unit from Motion Sound delivers Real Character and Real Rotating Sound that you can control and modify to your individual style.
The KBR-3D provides stereo Hi-Fidelity, 3D expand channels, and a 12AX7 tube pre-amped real rotary horn channel with stereo low rotor simulation. The rotary channel adds real 12AX7 overdrive and warmth providing classic rotating sound to organ and electric piano. A sereo Hi-Fidelity channel provides accurate transparent sound for piano and brass. A second stereo Hi-Fidelity channel adds lush 3D sound for strings and stereo pads. The unique angled cabinet provides incredibly wide sound dispersion and enhanced three dimensional depth.
