Moog Sonic Six

“PLEASE READ THE FOLLOWING DESCRIPTION CAREFULLY, I’m going to try and explain the state of this synth as best as I can:

So, this thing was an impulse buy that I made pretty dang recently. It set me back a cool $1500 plus tax.

This unit is serial number 1126, which was written on the plastic film on the front panel. The plastic was separating and had to be removed. I put the serial number back with a label.
It is a very early Sonic Six with a build date of November 7, 1972, as-per the inspection sticker hidden inside the keyboard section.

It was found untested, as-is, at an estate sale in western New York State, then it was shipped to me in California. I figured I’d take a big risk and see if it had any life left in it. Once it got here in one piece, I sourced a replacement power cord, and tested it out. It powers on and makes sound, but well… it’s not a happy camper right now:

Upon powering it on, all I initially get is a high pitched whine if I bypass the filter and contour (envelope) -It would seem the RIGHT side of the front panel is non-responsive, but the LEFT side of the front panel is showing signs of life and the controls (more or less) do what they’re supposed to do. I was able to play with the dual LFO’s when routed to pitch. The internal speaker does work, and the volume and portamento controls seem to work as well.

The keybed still has nice key action. No clacky keys, and it seems to be tracking notes somewhat, but not in a musical way. Every key seems to at least change the pitch.

What I did:
I tested it, took a look inside, and got the cobwebs and skeletons out. Looks all-original) No rust or oxidation, and no missing parts (as far as I can tell). The PSU looks fine visually, but probably needs new caps. (there are two big ancient ones)

I haven’t tested the PSU for weird voltages or anything. There was a crusty plastic film covering the entire front panel and some of the switches on the keyboard, but I got most of it off.

I did have to replace some screws. The ones that secure the keybed assembly on the bottom are new. The ones holding the front panel in place were already there, but they are not a perfect fit. One slider cap had a crack in it and it won’t stay on, but I will include it, along with a couple metal clips that I found inside.

Cosmetically, it’s pretty decent. Some scuffs, dings, and scratches, but nothing absolutely terrible.

Long story short: it powers on, it makes …SOME sound… but it’s not working properly and needs to be looked at and serviced by a professional tech who knows how to work on vintage synthesizers. I don’t know what it needs, but your favorite tech might! Sold AS-IS in vintage non-working order and no returns. ” Click here to search for synths on eBay

Roland Alpha Juno 1

“Roland ALPHA JUNO 1 Vintage Analog Polyphonic Synthesizer. Functions great, all keys and buttons working (portamento button requires a harder press but functions), all voices working, all keys and controls work great, screen in excellent condition (backlight is a little dim but clearly visible in low light). Volume slider cap is missing but not needed. With original power cord and photocopied manual. These Juno’s are getting harder and harder to find with everything functioning.

Sounds amazing… filters are not quite as characterful as the earlier Junos but the oscillator options (like PWM on sawtooth!) and chorus enhancements make up for that. Amazing phasey pads and drone atmospheres, and can get quite experimental when pushed.

Cosmetically there are some rubs on the finish on the sides and corners, a bit of wear on the front panel lettering and a couple of tiny indentations on the membrane panel, but these are pretty minor and presents as a very nice example.” Click here to search for synths on eBay

Roland Juno 106 with KIWI-106 Mod

“Juno 106 – “The One” – Kiwi Mod, Analogue Renaissance, Overlay, Recap.

This is “The One”: an early Juno 106 (metal portamento switch) in immaculate condition. Please see the pictures as they form part of the item description.

As you should hopefully know, the most common fault on a Juno 106 is failed voice chips. Which is why on this Juno, all voice chips and wave chips have been replaced with Analogue Renaissance chips. These chips are built to a very high tolerances, making them more reliable than the original chips, while sounding identical. Any Juno out there which has not had its chips replaced with analogue Renaissance chips is likely to have a voice chip failure. Be wary of any listings for Junos which have had “repaired” chips. Sellers often dip the chips in acetone which will temporarily fix the chips, but they *will* fail again. That is why you should always look for a Juno which has Analogue Renaissance chips, awkward it for an additional £500 to £600 to have some fitted.

The power supply unit on this Jumo has also been recapped, ensuring the voltages are correct and stable, prolonging the life of this Juno.

Also fitted is the Kiwi 106 CPU board, aka KiwiMod. This adds many features, such as an arpeggiator which was missing from the Juno 106 previously found on the Juno 60, it also adds a sequencer, additional envelopes and LFO. It also adds a superb UNISON mode with detune, making this Juno an amazing bass synth, as well as all the usual Juno sounds we all know and love. Also included is the optional swap backboard allowing the original CPU board to be refitted if you so wish. You should check out the Kiwi Technics website for full details.

Finally the unit has been fitted with the Kiwi overlay, helping the player navigate their way around the extra features which the kiwi mod brings.

Basically, this is the Juno you want, this is THE ONE!” Click here to search for synths on eBay

Roland Jupiter 8

“For sale is a rare Roland JP-8 with MD-8 Midi DCB Interface. This is a later 14-bit model and came from long-time original owner. It was hardly used over the years and kept in very nice condition.

If you have been waiting for just the right Jupiter 8 to come along, this is the one to own. Being in such clean shape it will make for a great investment, as it’s only likely to increase in value, plus considering it’s been serviced it will be in top operational condition on arrival.

– Full internal cleaning
– Cleaned sliders, pots and switches as necessary

Korg MS-20

” I’ll start by saying, the new versions are def cool, but not even close in raw tone. The original is still the real deal. These are quirky, cool synths… the best of Japanese Filters for sure. Gritty, gnarly and more. Two OSCs of sweet tone. Notice there is no screw on the VCA section panel.. this is an original 35 filter version.. known to be much more aggressive in tone and much rarer than the latter filters : )

Ive had this for years, used it for years on albums and soundtrack work. It always sounded killer, always stable too. I have never been one to do the modular/patching thing so that portion of this synth was never utilized.. I’m not that kinda guy : ) plus with as sweet as the standard portion of this synth is, i never felt the need to delve into patching. Couple of cosmetic things to note… there is a small crack on the right side panel.. never bothered me.. and the lowest white key on left is slightly tilted to the right. it still works/triggers fine, that never bothered me either.. been using it that way for quite a while.” Click here to search for synths on eBay
