 So this lovely Minimoog has sold, but they are our favourite analogue synth and we should have another for sale or coming up soon. You can see our current stock of analogue synthesisers here, but if you don't see what you want please contact us for a current stock list which will include incoming units available to reserve.

Soundgas are pleased to offer for sale this stunning early "MuSonics" badged Minimoog Model D in excellent cosmetic condition and perfect working order.
 It's in a finely-crafted Claro Walnut case (the original case was beyond repair), and has been extensively overhauled by a respected synth tech in the USA. Serviced by a top engineer and in superb operating condition.

It was completed in August 1971 by 'Kip' at the R.A. Moog Inc. plant at Trumansburg, NY.

It's a 110v USA model.

All hardware looks to be original (aside from the case). The attack and decay controls were incorrectly-wired from the factory - the attack knob controls decay and decay knob controls attack: it has been left in this original state (a simple fix to put right, but we felt it to be part of the synth's history/identity - as did the US synth tech who worked on it previously).

Extensive work had been completed on this synth before we bought it to ensure reliability and practicality - this is an early Moog you can play: the tuning and tracking are very impressive for a Mini of this age with its original oscillator board.

All boards have had new metal film capacitors and new electrolytic capacitors.

The trimmers have been changed on the VCA, VCO and power supply boards improved fine tuning.

The filter board has rematched transistors and sounds stunning.

An octave buffer board has been added to the octave selector which, together with the additional wiring on the switches makes for greater stability.

Did we mention that the filter sounds gorgeous?

This Moog synth sounds and plays every bit as good as it looks: a practical classic and solid investment. The filter is slightly smoother and creamier than later Minis - this Moog has that classic rich larger than life sound.
There are no known operational faults with this unit.
(Please note: it is always possible with vintage equipment that
some crackly pots/sliders may develop over time when equipment has not
been used - even during a short delivery period - this can usually be easily rectified either by use or with Caig Deoxit spray).

We also currently have two other Minis with original oscillator boards from 1972 and 1978 available.

Detailed photos are below - Youtube demo to follow.


We are passionate about supplying high quality vintage gear to our customers and go the extra mile to ensure complete satisfaction.

Shipping discount available if paying by bank transfer.

Tax (VAT)

Some of our gear will have VAT at 20% added in the UK/EU, but a lot of it won't. This should hopefully clarify the situation but if you have any questions then please get in touch.


  • These items will have two prices visible: with and without the tax.
  • If you are buying in the UK/EU you will receive an invoice showing the tax component.
  • If you are buying these items outside the EU when you get to the check out and enter your shipping location you will be charged the ex-VAT price.
  • VAT-free sales are also possible to businesses within the EU with a valid VAT number. You will need to contact us in order to buy via this means.


    • Much of what we sell is classified as "Second Hand Goods" and so while we still pay some tax, there is no recoverable/deductible component for sales to any part of the world.
    • So, the price you see is the price you pay wherever you are.


    • Shipping charges are also subject to VAT at 20% within the UK/EU - this is included within the prices you see for shipping to those areas - it is not shown separately in the cart but will be shown on the VAT invoice you receive with your goods.

    We are very experienced at packing and shipping valuable and sensitive gear worldwide. Binson Echorecs, large valve amps, vintage synths, rare racks, and even a CS-80 or two - you name it, we've sent it and it has arrived in one piece and ready to play.


    We keep it simple: if you buy more than one item you only pay the shipping on the item that has the highest shipping cost. This is the same no matter how many items you buy together (so the more you buy together, the bigger your shipping discount). If you check all the items out all together this will be calculated automatically at checkout. However, if you make an order and then wish to add to it before it ships please get in touch and we will refund the shipping on the item(s) that are cheaper to ship.

    Note that this also allows you to purchase add on items such as transformers and other accessories, and also t-shirts and other merch, without paying any extra shipping on them.


    CAN I COLLECT MY GEAR (and save on shipping?)

    Yes! If you want to use this option either get in touch before you purchase, or contact us afterwards and we will just refund you the shipping. Note that collection is by appointment only and only during weekday office hours.



    The shipping prices for our gear vary considerably depending on the type of gear, value and destination. To see shipping costs put the item you are interested in the cart and then either use the shipping estimator or go into the check out process. Or just contact us and we'll tell you what you need to know.

    It is a fact that, with vintage items, there are going to be times when gear arrives in need of some adjustment or calibration, and some times a piece of gear that was working 100% just chooses the day after arriving for a new fault to develop. However, having been working with sensitive vintage gear for many years, we are very experienced at dealing with these occurrences and will always work with you and get the problem solved as quickly and painlessly as possible.

    Note that we have have not entered automatic shipping for every country. The countries we ship to most often will have shipping rates and we are in the process of adding more shipping fees to the check out process. But if you are looking at an item that doesn't have the fee information you need then please use the contact page or call on +44 1773 856475.

    Which carriers do we use?

    We usually use Royal Mail, UPS and DPD/Interlink - it depends on the item and destination as to which is the most economical. If you have a preference then we should be able to accommodate it (but we may need to pass on any additional costs) - just let us know what you need.
