“Up for sale is a really great iconic synth in great condition. For those looking, Im sure that we all know the classic maintenance problems that vintage Junos can have: the old voice chips eventually all go bad and the bucket brigade responsible for the classic Juno Chorus is known to fail, along with scratchy pots and sliders. Not to worry on this unit, I recently cleaned all the sliders and pots with deoxit and they sound great, especially the volume pot which seems to always sound scratchy with time. The voice chips have all been swapped with the much desired Analog Renaissance chips, ensuring the sound stays the same but makes the Juno future proof for a long time to come.
The previous owner said there was an issue with the Chorus, where the VCA at max value would cause the Chorus to sound distorted. But upon closer inspection I researched and found the culprit to not be the irreplaceable bucket brigade chips but two transistors in the Chorus circuit. After replacing them the Juno Chorus worked better than ever. The only slight issue I could find on the Juno is the VCF frequency slider doesn’t seem to kick in until about the 4 notch, but then works perfect after that. Comes with really nice SKB hard case with wheels for easy transport.” Click here to search for synths on eBay

“YAMAHA CS15 Monophonic Analog Synthesizer. This is a great lesser known mono-synth which I’ve used extensively for both bass and lead sounds. It’s added secret weapon is the audio trigger input which is a super cool feature for adding dimension to other sources such as kick drums. Was serviced a little while back by top UK tech Tim Wallhead and is all in good working order apart from one missing slider cap on the pitch bender (see photos). Condition is “Used”.”

“Vintage Sequential Circuits Pro-One analog synth. Recently serviced and fully cleaned by Takeshi at Main Drag Music in Brooklyn. Fully working J-Wire keyboard and several upgraded and restored pots, keyboard bushings and wiring. Unit is in AMAZING sonic, mechanical and cosmetic order and we are reluctant to part with it. We have a Prophet 5 so most of our vintage SCI sound is covered, but this unit takes CV and Clock I/O as well as External Audio, which is a big part of the way we work with synths. You can bring anything into this filter and control the filter CV externally!! Can route tons of modular gear through this and it BLOWS AWAY most of the modular. The keys on this unit are a joy to play and rock solid. The arpeggiator works along with, basically, a legato mode on the keys that plays at the same time, and can be set to either transpose or add notes. It is a great feature and there is tons of tweakability on this synth – which makes it very special and why prices are only going up right now. There is one piece of gaffer tape we put over part of the fuse box, as it is inherently a bit flimsy and having it prevents any issues from fuse popping out for any reason. ”
