Yamaha EM-90 Ensemble Mixer *Soundgas Serviced*

1970s mixer amp with built-in spring reverb and unique drum machine.

Serviced and ready to ship.

This groundbreaking mixer/beatbox/spring reverb series was used by Mtume to astonishing effect when he played with Miles Davis (who’d been gifted this, along with a YC-45D organ by his Japanese tour sponsors, Yamaha) on the live Agharta, Pangea and Dark Magus recordings. Mtume put it through his Mu-tron Bi-Phase and controlled it with a volume pedal, using the beatbox more for texture (‘tapestry’ as he put it) than rhythm. 

This is the less common version without the later “A” – that one is black, silver and blue with hifi-type knobs, whereas this is an earlier vision in cream and green. While both the EM90 and EM90A sound very similar, we suspect it was the slightly later “A” that would’ve been presented to Miles by Yamaha.

Spec:

• Six channels with 1/4” inputs on the front
• Line, Guitar, Mic switch for each channel

CONDITION: Has some low level oxidation on some of the casing and other minor signs of age, but overall this is a great looking piece of kit. See the photos or get in touch for more information.

100v Japanese model - it will run on North American mains 115/120v without a transformer (we run all our tests using 120v power); however, a step-down transformer is recommended for extended use. A step-down transformer is required in the UK/EU. We do not recommend using cheap generic Chinese mains transformers and can supply a high quality UK-made unit if required.
