Product Description

Superb, clean Korg MonoPoly MP-4 vintage analogue synthesizer for sale in excellent cosmetic condition and perfect working order.

Complete with original hard case.

Price includes fitting of a new transformer for 120 or 220/240v operation.

Tubbutec ModyPoly Upgrade option available: this kit can be added for a cost of £350 + VAT. Video demo below. This kit adds various additional play modes, a free definable arpeggiator, midi in/out, a sustain pedal input and various other features. We have the kit in stock but this will add 1 - 2 weeks to the lead time. Read full details and hear demos on the Tubbutec site. To add the kit please message us after purchase.

Note that this kit can be further upgraded with the ModyPoly HiRes Upgrade to add microtonal support - see details and demos here - note that this adds an extra knob to the front panel. This adds an additional £100 to the cost.

Below are a couple of YouTube clips that demonstrate what this synth can do (with thanks to the uploaders); some effects have been added.


In superb cosmetic condition with minimal signs of age. Please see photos or get in touch if you require more information on condition.
