Re-Badged Rheem Kee Bass NDK Kee Boo Vintage 60's Analog Bass Synth / Organ
Note this is the first time, this specific model has been featured here on MATRIXSYNTH. Curious bit of synth history. There have only been two other NDK posts before this.
"Rare NDK 'Kee Boo' a variant of the Rheem Kee Bass Analog Bass Organ. Both share an identical circuit, only differences are the Black Sparkle opposed to Red Swirl and Boost knob instead of slider. This Kee Bass was recently serviced and had new precision locking tuning pots installed as some of the original pots had become faulty. The original power cord pocket shows No signs of damage, and the original power cord has had some hot glue added to reinforce the joints against pulling wear. The Tolex is in great shape. The plastic red jewel that cover the bulb is broken. The bulb itself is fine though. The chrome bulb surround is included along with the NDK badge that was originally glued over the words "Kee Bass" on the rear plate. Ready to play for many years to come! Extremely low sub bass, fantastic for Dub and electronic."

"Superb analogue drum machine dating from c1983. In excellent condition and working order following an extensive professional service.
These are uncommon in any condition, but this only the second example we've seen that works as it should. It's a ground-breaking historic analogue drum synth with onboard sequencer, designed to link up with either a Sinclair ZX81 (UK) or Timex 1000 (USA) personal computer to provide computer-programmed beats for the first time ever.
This example is in excellent condition - it has a few minor scuffs and dings as you would expect but it is looking great for its age.
Functionally it's in great working condition and it's wonderful to finally be able to program one of these machines - we've had several over the years, but most fail to retain programmed sequences for more than a bar or two before crashing. We must add the caveat that as this machine is based on ancient computer technology, we can only offer limited guarantees as to its future operating state: it works now, but we can't offer any extended warranty beyond a guarantee that it will arrive in working order: if there is any problem at all on delivery, please email us immediately.
Capable of a range of quality analogue drum synth sounds and, being one of the less-common and seldom-used drum synths, it immediately has an appeal if you're looking to stand out from the crowd.
This English drum synth/computer, designed in 1981 by Clive Button and launched to great acclaim a year or so later, was revolutionary but alas very short-lived; there are few surviving examples to be found in any state, let alone good working order. Originally used by Depeche Mode, the MPC-1 failed to replicate their successes and hit the big time and sank without trace, unlike its later namesake - Roger Linn's famed MPC series (no connection). It has an 8 bit processor and a massive 4kb of onboard memory to store programmed beats - these can be loaded/dumped via the tape in/out interface (not tested).

"Up for sale is our Classic Roland SH09 Analog Synth. This to me as well as many others is far superior in sheer tone compared to the more popular SH101. The oscillator section and filter section sound every bit as powerful and huge as our Roland System 100 Modular. Its a sound that no other synth can do. It may be limited but it makes up for that in the biggest basses and leads.. not to mention the craziest efx. It looks fantastic as it has never been gigged and it all works and sounds great!"
