If you're into vintage gear, you've probably come across our website. We've been buying, refurbishing and selling vintage synths and other electronic musical instruments for close to 30 years now. We're perfectionists and take our business, our gear, and our customers very seriously, so buy with full confidence - we won't let you down.

Our prices here may seem high, but we are a legit business with real business expenses, not your typical amateur seller with a Reverb store. Please click on our user name to read more about our shop so you better understand our prices & high standards.

Reverb and merchant fees are of course already added into our prices here.


This item is in perfect condition and appears to have never been used (apart from our gloved testing when we got it to make sure it's working right... and it is!). It comes with power cable and an original cardboard box. Any original packing materials that were originally inside the box were replaced with bubblewrap for shipment, so this is how we will ship it. We read that there were only around 100 of these made. How many others are in this condition?! You’ve gotta hear this thing - we posted a video of it to our website but we can’t post links here.  NOTE: The exact unit shown in the photos has been sold - this listing is for another in identical (perfect) condition - the only way it varies is in its serial number, possibly the color of the LEDs as Macbeth used different LED colors in some units, and the condition of the original box. If you are looking for a beautiful M3x, this one will certainly not disappoint.

This powerful 3 oscillator analog synth bears a resemblance to and is based on the classic Moog Minimoog but offers a much wider sonic palette as it features oscillator sync and cross modulation options that allow for complex wave shapes and FM tones that are lacking on the minimoog and most other synths. It's a CV gate synth under MIDI control, thanks to the fact that there's actually a Kenton MIDI to CV converter built into this model. This adds portamento, an LFO and other options. The M3X sounds incredible and will make an excellent addition to most analog synth players studios.
