PAiA 6710 Vocoder

” A PAIA 6710 VOCODER ASSEMBLED. A RARE DISCONTINUED ITEM. ANOTHER PAIA KIT I BUILT. EVERYBODY KNOWS WHAT A VOCODER IS.
GREAT FOR PROCESSING VOCALS OR OTHER INSTRUMENTS. THIS WAS OVER $175 WHEN I BOUGHT THE KIT WITH THE FACEPLATE AN EXTRA $26. IT HAS NEVER BEEN RACK MOUNTED. I TESTED IT WITH A CD FOR PROGRAM INPUT, AND A OSCILLATOR FOR THE MODULATOR, AND WAS ABLE TO GET A MODULATED OUTPUT. SWEEPING THE OSCILLATOR IN THE AUDIO BAND GIVE A INTERESTING COMB FILTER /TIMBRE SHIFT TYPE EFFECT, WHILE RUNNING THE OSCILLATOR BELOW 100HZ, GIVES A GATED TREMOLO TYPE EFFECT IT. IT ALSO HAS A SWITCHABLE FUZZ EFFECT. A/C POWERED WITH A INCLUDED REGULATED DC SUPPLY. THE OWNER’S MANUAL IS ON THE PAIA DOWNLOADS PAGE.”

PAiA Theremax

“Here we have a PAIA ThereMax Theremin which I built approximately 20 years ago and used very little.

It is 100% solid state and includes a “wall wart” DC power supply.

It is built inside of the PAIA wooden lectern case.

Very good condition! (this unit with the wooden lectern case costs over $230 from PAIA and then you have to build up all of the electronics and finish the lectern case).

Works as it should!

Note: there is a little bit of dust on the front panel knobs which I will clean off before shipping.”

Teenage Engineering OP-1

“Teenage Engineering OP-1 Keyboard Synthesizer with case and extras.

Purchased 11/13/17 from Musicians Friend and used for under two hours.
Comes from a non smoking home and has never seen outside the home use. I literally bought it, made the case and put it away in storage. I take it out once a month and give it a charge just to keep the battery happy. The battery indicator lights have never worked right… they do the usual OP-1 weirdness. They show its charging, but it never shows full. Pretty common if you look to the forums.

I built this case from an old “pov RC flight case”. It used to house a small monitor and some other flight equipment. Now it is home to the OP-1, which is plugged into a Belkin five way splitter, which is plugged into an Alfway bluetooth speaker. With this setup you can run the op-1 and four other instrument into the Alfway speaker. Its a pretty sweet setup for on-the-go blooping and bleeping. Ive included a list of everything you receive in this sale below, with a short description. Feel free to ask any questions!

Included with sale:
* (1) Teenage Engineering OP-1 with original case, overlays and rubber bands and charging cable. (firmware R.00225)
* (1) Teenage Engineering Antenna for OP-1
* (1 SET) DJ TechTools Chroma Caps (nice, easy to grab knobs… much better feel!)
* (1) yellow 3D printed crank
* (1) DIY Case (its not perfect, but its a great place for the op and accessories)
* (1) ALFWAY Bluetooth speaker with instructions. 10 watts. 3,000mAh rechargeable battery. Speakerphone. FM mode. Bluetooth wireless. Really cool little speaker that was bought for another project but fit this case really well. It can also be used as a power bank to charge other devices or phones.
* (1) Belkin 5 way splitter hub thing.
* (1 SET) 3D printed stands with rubber, non-slip feet. I printed them with a pretty high fill rate, so they’re pretty weighty. Good stand for table top operation though.
* (1) Printed manual in white binder
*** The only thing not included in the photo is the white charging brick. Thats mine and you can’t have it.” Click here to search for synths on eBay

Roland MC-202

“Roland MC-202 – excellent condition. Includes power adapter. This is an analog synthesizer/sequencer. It sounds very much like the TB-303 and SH-101 bass synths. Sometimes considered the “poor man’s 303″. It has a very evolved form of TB-303 like programming (more like the MC-4) and SH-101 like controls of the VCO, VCF, VCA, LFO, Envelope and Mixer sections. The LCD display is a great feature too.”

Yamaha CS-50

“This is a fully functioning clean synth! Comes with original manuals, ID Warranty card, and the original pedal with case and legs. The exterior case in in decent shape. It has some marks and dings. I had this synth serviced in Portland, Oregon by Control Voltage. It has been in my personal synth collection the last 10 years. It is missing one input volume knob on the back exterior panel. (see photo). You can still easily adjust the level. I babied this thing and it sounds amazing! I am offering 200$ shipping and insurance on this item. If you pick up the synth in person however, I will refund you 300 dollars off the sale price. I would much rather it picked up in person than shipped due to its age and value.” Click here to search for synths on eBay
