If you are viewing this page I am sure you know what this thing is capable of. It was designed by Bob Moog and is quite literally one of the most powerful mono synths ever produced.
Lots and lots of modulation possibilities and filter options, to quote Sound On Sound “you’d be hard pressed to emulate its intricacies using a modular instrument”
It’s also an unbelievably rare piece of kit, somewhere in the region of 250 in existence.
Fully serviced and in excellent condition, just got it back from my technician today.
Things worth noting.
1. A couple of the original knobs are missing and were replaced by yellow ones by the previous owner. (Photo 6)
2. Wooden side panel has suffered a crack. My tech says it looks like somebody tightened the screws too tight and it was caused by the ensuing pressure. (Photo 9)
3. Scuffing to lower frame under keyboard and slight chip to underside of 1 key. (Photo 10)
4. Selling to cover a tax bill. Really regrettably. Always thought I would hold on to this forever.
5. There are some other light scuffs and scratches, which were very difficult to show in the photos.
6. I will NOT post this item. However I will deliver free of charge to any buyer in England or Wales. If you are outside of this area you will have to pick the item up yourself, in person. NO COURIERS."
