This is fortunately out of sight. No apparent marks on the front panel. All sliders and switches work without noise. Lovely condition with no niggles or faults. My very first synthesizer!

“Yamaha CS-5 Vintage Analogue Synth with Kenton filter CV socket upgrade.

A great vintage mono synth if you’re on a budget, great for fat squelchy bass lines.

In working order but would benefit from a service as a few of the pots are a bit crackly or have dead spots (listed below). Should be a relatively simple job of replacing the pots.”

This is a rare initial model. Cv / gate in / out terminal mounted. It has been maintained by the vendor.

Because the color tone on the keyboard is cheap!” Click here to search for synths on eBay

Teenage Engineering OP-1

“Legendary Teenage Engineering OP1 Synthesizer purchased in December 2016 but hardly used. If you don’t know it, the OP-1 is an all-in-one portable synthesizer, sampler and controller. with additional features like a built-in FM radio and an assignable G-force sensor for motion controlled effects, there is quite nothing like it.

It’s modular architecture enables endless sound possibilities without making the workflow complicated or distracting. The compact design and real physical interface makes it inspiring to create music, no matter who you are or how experienced you are.

I have decided to sell it as I am more into designing my own sounds on the computer, although the OP1 is a very full capable synth. I estimate it has only been switched on for about 30 hours altogether so the battery will be in excellent condition. ” Click here to search for synths on eBay
