OB-Xa, Oberheim @ 19 March 2019, “No Comments”

“Oberheim OB-XA vintage analog synthesizer. This is an original factory 6 voice model. The synthesizer is not working properly. There is a tone or noise, depending on which knobs you turn but no patches. All voice cards are working and light up one at a time when you trigger a note but they are out of tune. When I purchased the synth, all 6 voice cards already had new capacitors and all multi trimmers replaced. The power supply had also been recapped along with all new key bushings installed. The previous owner could not find anyone to do a calibration so decided to sell it. I also cannot find anyone to do a calibration within 7 hours of my home. It may need more than a calibration or it may not. It has scratches on the panel of synth and wear to the side panels. I am selling it AS IS or for PARTS only. Each voice board alone can sell for over 900.00 each. I am tempted to part it out because I can probably get a lot more money for it, however I really do not want to part it out over a one or two year period but stay tuned if I do not sell it. It is super clean inside as seen by the photos. I pack well and ship quickly. ” Click here to visit listing on eBay

PAIA @ 19 March 2019, “No Comments”

“This is a real treasure and a great learning tool for synthesizers. This multi-voice synthesizer from the mid-1970s was built from a kit and worked when it was retired, though I can’t promise it will now. It is solid-state, though, so why not? The schematics, procedure instructions, glossary, and setting/operating instructions are included so you can experiment away. Learn how the various electronics produce the sounds and learn how to control them. This is a nice, quality device.

The build instructions have been marked by the builder, so I won’t claim this is mint.” Click here to visit listing on eBay

“Up for auction is an OP-1 synth in perfect working condition. I bought this hoping it would get me back into making music, but alas it’s just been sitting in a drawer for the past year.

There are no scratches/blemishes on the unit, and the system test confirms that all keys/knobs are functioning (see green screen in pic). Includes USB cable, original box/packaging (styrofoam box w/ rubber bands), and plastic overlay thing seen in pic.” Click here to visit listing on eBay

“Only 2 owners. Purchased from a Pawn Shop in 1982 Los Angeles. Excellent condition. Works as it should. Serviced recently. One cool coffee ring on the side wood panel. Sounds extremely fat.

Casio, SK-5 @ 19 March 2019, “No Comments”

“Travel back in time with this early Casio sampler. Made in Japan from about 1985 to 1987, it’s a very early sampler. This is the same model of sampler that Terrence Howard started with in the “Hustle and Flow” movie. It made sampling available to the masses cheaply.

It can hold four 0.7 second samples or two 1.4 second samples. The samples can be looped, reverse, and hit with a handful of effects. It’s also a 32-note keyboard with four-note polyphony. Its eight voices are piano; dog; trumpet; chorus; vibraphone; surf; pipe organ; and flute. The rhythm pad has hi bongo; low bongo; laser gun; and lion. That’s right: it has some weird sounds (dog, surf, laser gun, and lion). It also has a eight basic tempo-adjusable rhythms. And it can record song loops for later playback.

It runs five AA batteries. It does not come with the power cord. Output is 1/8″ jack. Input is either 1/4″ or 1/8″ jack. The Owner’s Manual is available for free online at Yumpu.

It’s a cool retro piece. I tested it, and everything works.” Click here to visit listing on eBay

Micromoog, Moog @ 18 March 2019, “No Comments”

“This classic synth is in very good condition. It’s everything it should be. Lots of information online about them.

Comes shipped in a nice, good condition road case.” Click here to visit listing on eBay

“The Moog Micromoog is a one-oscillator (plus sub-oscillator) classic Moog monosynth from the ’70s.

It is capable of the classic “beefy” Moog basses and typical Moog synth “whistles”, but also of a lot more.

It features a very cool routable S&H circuit that one can even use to simulate an arpeggiator or a sequencer, and many other modulation & routing options that make this little synth very versatile.

If you’re looking for “crazy” synth sounds you will also find them in abundance here.

It was a budget unit, so the overall construction might not be as “strong” as the Minimoog, but it’s still fairly strong, and it is very portable.

It features a ribbon controller instead of the more customary pitch wheel, while it does retain the usual Moog modulation wheel, which you can use to control several parameters.

The filter is unmistakably MOOG, and you can also process external sounds through the Micromoog –
very useful feature.” Click here to visit listing on eBay

MG-1, Moog @ 18 March 2019, “No Comments”

“Foam is removed and overall good condition. There are very small chips in the front of 2 keys. See photos.

This MG-1 has a lot of mods. I can only guess what some of them are because they are not labeled, however, I’ve included photos of the wiring to help you figure it out.

Here’s what I can tell you about the mods:

Rear RCA jacks were changed to 1/4″ and it’s now V-trig for easier sequencing.
The output volume seems louder than stock.
I think the detune slider has been changed to go down a full octave.
The switch on the left drops the keyboard down one octave.
One of the knobs on the left changes the 2nd oscillator’s pitch. I think it detunes.
I think the knobs on the right are FM for Oscillator 2 and PW/PWM for Oscillator 2 square wave.
The lower switches on the left and right route what’s happening on the knobs to the LFO. ” Click here to visit listing on eBay

D-50, Roland @ 17 March 2019, “No Comments”

“Vintage (1987) classic/legendary Roland D-50 Synthesizer in excellent condition. Rubber contact strips were replaced by new ones about a year ago. A complete cleaning of the Keyboard contact board was also performed before placing the new contact strips. Slide potentiometers for Volume and Aftertouch were also replaced by new ones. The entire synthesizer is perfectly working.

One of the cleanest and greatest D50s you will see in a while for sale.

I’m also including a SKB 61 Key Hard Case, in very used condition but still solid, reliable, fully functional and a great way to protect the D-50 during shipping and to be used for gigging/traveling with the D-50 or any other standard 61 Key Synthesizer.

Original 2-prong power cable and original printed manuals also included.” Click here to visit listing on eBay

“This will ship with insurance of the full price, and require signature. All included in the free shipping within the US.

Jupiter 6 with Europa mod comes with hard case, and power cord (might be original since it fits perfectly, unlike other 3rd party power cords)

I’m not the original owner. Bought this off of eBay back in April of 2006. Kept in a smoke-free and temperature controlled home studio.

Never played shows with it. Decided to let this go to make room for some new things. Front panel and all the graphics are pretty much

flawless for a synth this old. All buttons, sliders, knobs, keys, switches, pitch bender, MIDI, audio outputs, pedal inputs, and lights work

as they should. Haven’t checked the arpeggio clock in, and the tape load / save ports. No point since this has the Europa mod.

The tape load / save feature can be kinda sensitive if imported / exported at the wrong volume. Has all 4 rubber feet on the bottom.

Functional problem:

The 5th voice on VCO 2 is bad. Some patches it’s completely dead and other patches it sounds a little off from the other voice chips.

It was completely dead before so I replaced the amp, and voice chips.” Click here to visit listing on eBay

It has been fitted with the Moog slayer mods for control of cutoff and resonance via the knobs on the side. There is also a third knob for FM. The order of these from left to right goes; cutoff, resonance, fm.

The only issues are that the battery cover is missing and the cap for the tune slide pot is missing.

Keytar, Korg, RK-100 @ 16 March 2019, “No Comments”

“It is used only twice after buying it for secondhand 30 years ago, but there are fine scratches.

The color is very rare with a rare walnut (wood grain).
It is a rare product that is rarely offered for sale in the second-hand market.

The power is turned on, and it has been confirmed that a sound can be output from the MIDI source connection.
By the way, since it is a remote keyboard, it does not emit sound from the main unit itself.

There is no special case.
I will attach the case of a photograph, but I can not store it completely.
There is also no strap.” Click here to visit listing on eBay
