Korg Mono/Poly

Korg Monopoly for sale, meticulously refurbished over approximately 16 hours, resulting in an instrument that works better than the rest...and is justifiably pricier, but is ready to use professionally. The person who sold us this unit said it was working fine, but in reality, it had several significant problems and needed a full and costly overhaul, including a $200 part (and others).

Here's a list of some of the work we did to this unit:

Cleaned unit inside and out.
Rebuilt power supply (replaced electrolytic capacitors) (future-proofing measure)
Replaced all electrolytic capacitors throughout unit (future-proofing measure)
Recalibrated. All ok. 
Cleaned all potentiometers.
Cleaned all switches.
Cleaned all key contacts. 

The MP-4 is either a 4 oscillator monosynth or a 4 voice polysynth. Packed with lots of cool features (cross modulation, oscillator sync, 2 LFOs, etc), this synth packs lots of power. Ghost Culture recorded a whole album with this keyboard - check out his track Giudecca, it's one of our faves, and made us realize we needed one of these in our studio too.
