This is legendary Roland Alpha Juno-1. From this synth you can find THE hoover sound as a preset! On top of that Alpha Juno-1 is capable of huge amount of other sounds including lush Roland style strings, basses, brasses, sound effects etc, all useful still today. Alpha Juno has been titled as a workhorse for techno and rave sounds but of course can be used for other genres too.

This particular unit is in 100% working condition. Battery inside in on good health. It is also in nice cosmetic condition with only minor scratches here and there. On one corner the plastic casing has one crack (see pictures). It is 220V version. Power cord included.

What internet says:

The Alpha Juno is a great sounding Juno type synth! Not quite as warm in sound as the previous Juno's but still a nice addition to any techno synth rig. Sliders and buttons were replaced by membrane buttons and the Alpha Dial which is used to edit and browse through the extensive selection of parameters: DCO digitally controlled oscillators, LFO, bend, ENV, pulse, waveforms, noise, PW/PWM, high pass filter, VCF (filter) with freq/env/res/LFO/kybd, VCA envelope, chorus, and more.

Other nice touches include better MIDI implementation than previous Roland synths, 64 presets and 64 user patches, a nice LCD display, an LFO capable of a very slow rate for some cool sweeping effects, and a great bass sound (especially nice for acid basslines) and noise effects! It also has chord memory which is perfect for rave & techno, portamento and keyboard transposing.
