"This unit was previously modified to include an audio output jack for vco2. This allows frequency modulation (FM) of the oscillators or filter which nicely expands this examples sonic palette beyond a stock 400's.

We did the following work to this unit. The items at the top of the list are things we consider normal servicing. The ones at the bottom labelled preventative are future-proofing measures that other sellers rarely take (they often don't even service them either).

Cleaned inside and out.

Replaced power cable.
Cleaned and lubed switches and pots.
Replaced jack washer nuts.
Replaced some screws.
Replaced all electrolytic capacitors - preventative.
Calibrated vco1 vco2 cv exp cv - a must after a recap.
Replaced IC socket (14pin x 16) - preventative.
Replaced all pins inside multipin connectors on unit and inside connector cable - preventative."

"This Polaris 2 was fully electronically restored and is now in like new perfect working condition. And yes, of course the membrane panel that always breaks has been replaced with a brand new one so you won't have to worry about replacing it. We don't mess around here.

sn50033x

Here's what we did to this unit to make it perfect, along with some preventative stuff other sellers rarely do...because we want this unit to hopefully outlast others.

Replaced power supply electrolytic capacitors (future-proofing)
Reflowed some solder points as a preventative measure.
Cleaned unit inside and out.
Replaced membrane panel (we consider this a necessity even in the rare cases where they're fully working, as they eventually break - panel cost is $250 + installation labor, which is of course embedded in our price)
Cleaned and lubed all slide pots and levers.
Cleaned jacks.
Cleaned key contacts.
Removed original battery and replaced with new lithium battery (3v D type)
Recalibrated.
Replaced high and low output jacks.
Replaced operating system eproms with latest version 11 (originally was version 5)

This process took 11 hours of highly skilled vintage synth tech time, plus parts costs. The result is a perfectly working instrument that's ready to play, without having to pay another tech to do what we did and to wait months to years for another tech to do it."

"The K4 from Kawai can be thought of as a warm and fuzzy digital synthesizer. A sample-based digital synth, its sounds are those typically weird industrial type sounds that can still be useful in lo-fi, big-beat and trip hop music styles. The sounds are 16-bit preset PCM samples of acoustic instruments. However, unlike its predecessor the K1, the K4 adds a welcomed digital filter section. This truly makes the K4 more flexible, fun and useful for today's filter tweaking music effects!

The XD5 is an awesome drum synth module that has 256 waveforms, four of which can be combined to create a drum sound. It also has great resonant lowpass filters and envelopes for shaping the sounds and is excellent for techno, electro and industrial drums. For effects, a delay type effect is possible as well as a ring-modulator. It also has stereo outputs plus 6 individual outs for the studio pros. Mouse On Mars might use it.

The MM16 is a multi-purpose MIDI data processor with 17 front panel faders. Each of the sliders can be assigned for continuous controller information over any one of 16 MIDI channels, a "velocity mode" that uses the 16 sliders to become a "graphic EQ" for velocity data, and a system exclusive mode for transmitting system exclusive information to control individual synthesizer functions. Setups are included for Kawai K1, K4, K5, Yamaha DX7, and Roland D50. The MM16 can merge two MIDI signals, and can perform MIDI channelizing. You can also use it as a control surface for DAWS"

"Classic 80s 8bit PCM drum machine, used in countless hits.

This particular unit was serviced:

- all electrolytic capacitors were replaced

- switches and pots were cleaned

- latest firmware eprom was installed (3.0)

- factory patterns were loaded

- MIDI interface was added, built using the original E-mu design. This allows you to trigger the 12 sounds over MIDI dynamically

- comes with 4x additional eproms containing the famous LinnDrum LM2 sounds. I made a video a few monthes ago comparing 2 drumulators with stock and linnDrum kit if you want to hear the difference (youtu.be/k_EuRlCi_Vk)

Works perfectly. Cosmetic it is in quite good condition with some scuffs here and there, and also 2 holes were drilled in the back from a previous owner (no idea what was the reason). Unit is 230v."

"This unit was meticulously refurbished over approximately 16 hours, resulting in an instrument that works better than the rest...and is justifiably pricier, but is ready to use professionally. The person who sold us this unit said it was working fine, but in reality, it had several significant problems and needed a full and costly overhaul, including a $200 part (and others).

37383x

Here's a list of some of the work we did to this unit:

Cleaned unit inside and out.

Rebuilt power supply (replaced electrolytic capacitors) (future-proofing measure)
Replaced all electrolytic capacitors throughout unit (future-proofing measure)
Recalibrated. All ok.
Cleaned all potentiometers.
Cleaned all switches.
Cleaned all key contacts.

If you have one of these you’d like properly restored, we can help!"

Blue Roland SH-101 Monophonic Synthesizer

Note: links to listings are affiliate links for which the site may be compensated.

"Roland SH-101 (1982-1986), 1-VCO monophonic synthesizer with sequencer.

Compact yet just perfectly sized, plastic but sturdy, simple yet full of useful features. Not only one of Roland company's best looking designs, it is also a rare foray for Roland into 3rd party ICs - Curtis Electromusic's CEM3340 VCO chip granted SH-101 its distinctive rich tone. Needless to say that SH-101 defined the sound of IDM, early house and techno, and still rocks on!

This is a rare blue model that has been carefully serviced inside and out, which included replacing all of the electrolytics, cleaning all of the potentiometers, replacing some unstable sliders, as well as performing general cleaning. All the functions have been tested and re-tested.

The cosmetic condition could have been described as excellent if not for some of the plastic screw posts _inside_ the case. Those are notoriously brittle, but have been restored to the best of our abilities."
