“Up for sale is a Yamaha CS01 synthesizer with gig bag! This little analog synth is in good working condition, though it does have a few scuffs here and there, and the octave selector for the VCO is a little crackly. In addition, the battery cover seems to be a homemade job by a previous owner, but does a good job of holding the batteries in.

This synth was also modified by a previous owner so that the filter resonance is adjustable via the VCF breath control knob on the left-hand side. This is a rather nice modification since the stock CS01 only has an on/off switch for filter resonance.

Both the strap pegs are still attached so you can easily use it on stage! The gig bag is also in good shape and provides a decent amount of padding during transport. The entire synth will be shipped in a sturdy box for protection.” Click here to visit listing on eBay

“Yamaha CS01 for spares only. Condition is For parts or not working. Dispatched with Royal Mail 1st Class.

This early 80s budget analogue synth has been well loved but has become a bit bruised over the years. It will still make a noise, but not reliably, so probably best to sell for spares.

There is damage to a couple of keys and a missing slider cap (see pictures), otherwise intact.

Has headphone and line out jacks but is pre-midi so no other outputs. Inputs for breath controller and ac adapter (neither of which is included). ” Click here to visit listing on eBay

” Yamaha CS01 vintage analog monophonic synthesizer. This synth is mostly broken, and is really suitable only for parts, or only if you really like the sound of an analog keyboard that’s on its last legs.

The good news is that there are no dead keys and the outputs work.

Here’s what’s broken that I’m able to identify:

• The internal speaker is not in great shape.

• There is a quiet (but noticeable), high-pitched tone at all times, modulating up and down in pitch, like a quiet siren.

• The white noise generator is broken in a way that affects overall operation. It doesn’t reliably produce white noise on its own. In addition, an amount of white noise comes and goes at random (and especially when adjusting the VCF EG slider), even while using other wave forms (triangle, pulse, and so on). The sound is akin to laptop speakers failing.

• The VCF EG slider doesn’t seem to apply any kind of envelope to the filter: just random white noise.

• The VCO Pitch slider I believe is broken.

Does not include power supply.” Click here to visit listing on eBay

“Synth is in great shape and perfect working order. It takes either batteries or included 12volt adapter, not the original but a modern and better adapter. All functions work well and the keys are undamaged and still good and springy. I tested it on its own speaker and through a keyboard amp and performs flawlessly. Running through the controls you can here definite sounds from the eighties ( eurythmics, depeche mode, omd etc ). A really well kept bit of vintage kit.”

“The synth powers on and makes noise..

However the machine is not working properly 100% of the time. The machine is temperamental.

The sliders function…

Knobs function…

There is one dead key and it is pictured.
Cosmetically it is not the prettiest.

Initially it seemed as though the keyboard was not working properly.” Click here to visit listing on eBay

“Yamaha CS-01 vintage analog synthesizer with case, strap, and Yamaha power supply. Item is in great shape and plays well. This is a great monosynth capable of very deep basslines. The model was reportedly used for basslines by Steely and Clevie of Jamaican dancehall fame. The synth has some slight discoloration/fading above the keyboard and some discoloring, scratches and paint chipped off (see final 2 photos) around the sides and back of the casing, but is otherwise in good shape for a vintage item. No battery leakage. Battery cover is included. Foam inside battery cover has darkened with age. Internal speaker works or synth can be connected to external amplifier. Carrying case is original and has some discoloration/staining probably rectified with a handwash. Strap ends are on the synth and the strap is included if you want to play it as a keytar.” Click here to visit listing on eBay

“First introduced in 1982, the Yamaha CS01 has been recognised by today’s electronic musicians as a very creditable synthesiser. It can run on batteries or 12volt power supply (not supplied with this offer). In excellent working condition with just a few minor blemishes on the casing.” Click here to visit listing on eBay

Yamaha CS01II

” You are bidding on a fully working Yamaha CS01-ii analog mono-synthesizer. The unit is in great condition, with only a few scratches on the bottom. I took the unit apart and inspected it and cleaned it where I could. All of the knobs and faders have been tested for proper operation. All of the keys work and I cleaned in the contacts on all of them. The unit works with both 6AA batteries or when plugged in (12V power supply IS included!). The circuitry looks to be in great shape (see pics).

This is a super cool synth from the 80s and sounds awesome. I’m amazed at the sounds I was able to get out of it being such a small compact unit from the 80s. This is is the second version of the the CS01, and apparently was the last analog synthesizer produced by Yamaha before they went digital. If you have been looking for a CS01ii, this is a great example.” Click here to visit listing on eBay
