 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 OFFER FREE SHIPPING TO THE UK! There are some exclusions for distant areas and islands (see below), and also some occasional exclusions for very large/heavy/valuable items which will be clearly noted in the item descriptions.


    • You will need a bespoke shipping quote!
    • Our shipping calculator on here won't give you the right figure (and may well not give you one at all).
    • Please get in touch via the contact page and we can give an accurate shipping figure for multiple items.
    • If it is outside office hours and you are concerned about missing a piece of gear then buy it at the quoted shipping rate, send us a message saying what else it is you want to add, and we will deal with the discount once we are back on email.
    • You can do this with absolute confidence that we will give you a full refund if the final shipping quote is doesn't work for you.


    We are very experienced at packing and shipping valuable and sensitive gear worldwide - Binson Echorecs, large valve amps, vintage synths - you name it, we've sent it and it's arrived in one piece. Obviously from time to time with vintage items there are 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, we are also very experienced at dealing with these occurences and will always work with you to solve the problem

    The shipping prices for our gear vary considerably depending on the type of gear, value and destination. Currently the only way for you to see shipping is to 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.

    Also 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 07543 855788.

    If you are considering a purchase and want to check you have our best rate then please always contact us direct and we will give you an exact figure.

    Also note that for some items we are able to discount shipping to North America - continental USA and Canada. The fees you see at check out will take this discount into account. But if you have a question... you know what to do.


    We 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).


    We are not able to ship free to some of the UK islands (e.g. Channel Islands) and also to some of the further reaches of Scotland. If you think you might be in one of those area and want an accurate shipping quote before you buy then please get in touch.

    There are also some items which we cannot offer free shipping on to the UK. These will be clearly noted in the description.
