"Like nearly all the high end vintage analog synths we sell, this item has been METICULOUSLY disassembled, cleaned inside and out, FULLY serviced by professionals who’ve been servicing and selling vintage synths for more than the last 3 decades, and systematically tested multiple times over a long period to ensure it’s working exactly as it should. No BS. No ebay surprises. We’re perfectionists and don’t cut corners. Although this instrument came to us in relatively good shape, we want our items to be better than the rest and invested *many* hours of tech time plus parts costs to fully overhaul this unit so it would be clean, working like new again and as reliable as possible for its next owner. This was a serious investment of time, love, and money, and was definitely worth the effort and is of course reflected in the higher than usual price. If you’re looking for a great sounding example of this model that works just like it should without needing to invest hundreds or thousands of dollars in tech fees and waiting from weeks to years, this one should make you very happy.
We’re happy to announce we’ve got another meticulously refurbished Voyetra Eight with keyboard ready for sale. This unit took us approximately 76 hours of skilled vintage synth tech time plus parts costs to get it up to our high standards.
This work included not just getting everything working perfectly, but also applying custom modifications to make tuning better than it was when it left the factory, as well as taking future-proofing measures that other sellers don’t do, but that will hopefully keep this one running well a lot longer than lesser examples you may find.
After 76+ hours of restoration by our very experienced V8 expert and our focus on perfection rather than cost, you won't find a better one."

"This hard to find MIDI sound module was designed to sound similar to the classic Roland TB-303 Computer Controlled Bassline used all over acid / acid house music, techno, etc. This unit was tested and is working. USA only for this item."

"Professionally refurbished.
Features the Plus! upgrade by PointSource. OS 2.2.
In addition to any necessary repairs, our tech did the following preventative work that should add value to this fine machine:
Replaced data slider
Replaced all tact switches
Replaced pads
Replaced power supply capacitors
Installed new OLED display that's much better than the original (see pics!)
Cleaned and lubed all pots
sn0041x
Sample memory 512k = 16kHz 33.5 sec, 42k 12.5 sec
The restoration process cost us a total of 12 hours of skilled vintage synth tech labor plus parts costs. The end result is a professionally serviced and professionally sold beautiful example of this hard to find sampling drum machine that's better than the rest and is priced accordingly. You get what you pay for."

"Here’s a poor condition, non-functioning Roland TR-909 for parts or repair. Our tech says he’s confident he can repair it because he’s amazing and can fix just about anything. However, we pay him by the hour and projects like this tend to take a long time and cost a lot, and in the end, even if we made it look like new on the outside, there’s a cracked circuit board etc inside that wont look so good even after repair, so the end result would be a 909 that wouldn’t be up to our high standards. So, we have decided to sell it broken and strictly as is. Please take a good look at the photos to see what’s included and what’s not - theres nothing more and nothing less than whats shown. In recent years, there have been 909 clones on the market that reportedly use compatible parts one can buy to fix real vintage 909s. Please research this yourself if you’re considering buying this 909 and have the skills required to tackle this project as we dont want you to be disappointed. We also need to make it clear that there are no guarantees whatsoever, warranties, refunds or returns. We don’t know if you have the skills or access to the parts required to repair it. For the right person who enjoys fixing gear as a hobby and is really good at it, this may be a fun project. If it fails to sell, we will keep it and may eventually refurb it for use in an incredible public access vintage synth studio we may one day open here in NYC. Thanks for reading."
