Wow, a motion-sound leslie built into a Kustom head cabinet, what a great idea!(Just the thing for pairing with a Kombo organ). Was it difficult fitting it in there? I'm not terribly familiar with the motion-sound stuff - what are all those knobs on the front for?

It was pretty easy. The motion Sound KBR-M is sort of deep so it sticks out about 8 inches from the back of the K100 cabinet - that part is covered with plexiglass so you can watch the horn spin.
Basically, six knobs are for the rotary section, and six knobs (vol, bass, treble) are the two non-rotary channels.
Rotary Channel
1)Pre-Gain sets the amount of drive to the 12AX7 tube for overdrive/distortion.
2) Post-gain volume
3) Contour controls high frequency cut, adjustable from 4 kHz to 7 kHz. (3 dB Oct.)
The Rotary Channel Crossover is 800 Hz. The low rotor simulator is mixed into the Hi-Fidelity power amplifier. The Rotary horn has a built in microphone with level adjustment to the XLR line output.
4) Low rotor volume adjusts the balance between the horn and low rotor simulator.
5) The bass control EQ is at 100 Hz.
6) Low Rotor effect adjusts the level of the simulator.
Speed control is via footswitch -Fast, slow, and stop.
Non- rotary (HI Fidelity) Channels
The Monitor channel (1) has one input, volume bass and treble controls. The rear panel has a switch to disconnect the XRL line out signal for Vocal monitor.
The Normal channel (2) has one input with volume, bass, and treble controls.
The rear XLR line output contains the rotary channel's horn microphone and low rotor simulator along with the Monitor channel (if the line out switch is on) and the normal channel.
The rotary horn amplifier = 45 watts RMS
Hi-Fidelity/low rotor simulator amplifier = 130 watts RMS.
This model is from 1999 and I have to give Motion Sound a lot of credit for how well this unit works and its complexity – it contains a real horn and motor, motor controller, two amplifiers, a tube preamp, 3 channel preamp/mixer, active crossover, low rotor simulator, microphone, and XLR-out.
