Toyo Gakki Ult Sound DS-4 Analog Drum Synth

[LISTING UPDATED: this unit is now fully serviced and has had new sliders added] 

An Ult Sound DS-4 for sale – a great-sounding ultra-rare Japanese four channel analogue drum synth made by Toyo Gakki and as used by Yellow Magic Orchestra. 

In very good condition; it's just been serviced by James Walker at Synth Repair Services and sounds great. 

Minor scratches/chips to finish - some paintwork retouched - some slider/switch caps were missing and have been remoulded (they are of a lesser quality than the originals). 

Some crackle may happen when pots/sliders not used for a while.

Serviced and in superb working order - presents very well indeed - please see the detailed photos below to assess the condition for yourself.

An unusual and versatile drum synth: trigger via a drum pad, drum machine or output from your DAW. Check the Youtube demos below to get an idea of what’s possible - along similar lines to the great Pearl Syncussion – we usually have one for sale: see all our drum machine listings at:

Uses a 12v power supply - the original Japanese 100v supply can be included if required.

There are currently no known operational faults with this unit - some crackle may be possible when the unit has not been used for some time - this should clear with use.
