"Meticulously serviced and working perfectly. We replaced all the tact switches with new ones for flawless operation (they usually retrigger these days), cleaned and lubed all pots, resoldered stuff that often develops bad solder joints, cleaned things up inside and out, resoldered battery terminals, cleaned jacks and tested all functions and everything appears to be working exactly as it should.
The work we did to this unit to make it operationally better than the rest should add value to anyone buying one of these as it's work you won't have to pay another tech to do. This work is embedded in its higher than usual price. This item will be packed right so it arrives intact too. You get what you pay for."

"Freshly serviced by professionals (us) and in perfect working order, unlike most. The tact switches on these often go bad and cause the keys to retrigger, making it frustrating if not possible to accurately enter new patterns. We paid our tech to replace all these switches so they would work right the first time. He also cleaned and lubed all pots and resoldered jacks and pots. This is stuff we typically do to our 303s that most other sellers don't bother doing. This unit's been fully tested and is working perfectly. We'll give it one last test prior to shipping - we test our items multiple times because quality control is our top priority here."

GRP A4 Analogue Synthesizer
Note: Auction links are affiliate links for which the site may be compensated.
via this auction
"The Grp Synthesizer A4 is a direct descendent of the flagship A8, providing the same analog sonic power and flexibility at a fraction the price. Ideal for everything from smooth Minimoog-like leads to distorted, tearing bassline sequences, the A4 is equipped and ready.

Roland System 100M (112, 121, 130, 140, 150 modules) w/ 181 49 Key Controller
Note: Auction links are affiliate links for which the site may be compensated.
via this auction
SNs:
112 112228
121 101915
130 111976
140 102603
150 800892
The individual module SNs match this previous listing with the 4CV 184 keyboard.
"This was recently serviced by Belltone Synth Works just outside of Philadelphia. The sliders and pots have been cleaned, modules repaired, and it has been calibrated to Roland's specifications. This particular 100M comes with the 112, 120, 130, 140, and 150 modules as well the model 181 49 key controller.
There is the slightest dent on the top of the controller (see photos for condition). The keys are a little loud / clacky. The modular itself is in very good condition. There is some wear (once again, see photos for the condition).
I am including 5 cables to connect to modules to the cabinet-- one of which is NOT original. I am also including the longer din cable that connects the controller to the 100M as well as a handful of patch cables.
Most of these System 100Ms are 100V. This one is no exception. It would be best to use a stepdown transformer to convert US mains voltage to Japanese mains voltage.
This is a well cared for System 100M. I am selling it because I need to make space in my studio. Testing it out before listing it, I was tempted to keep it. Alas, I just need the space."

Video in the listing previously posted here.
"The Moog 'Sanctuary', of which only 100 units were ever made was the brainchild of David Van Koevering. Moog Music brought Van Koevering in to guide their marketing efforts when the company had developed a stronger national presence. David worked with local church groups to find a unique marketing outlet for a custom-named set of Moog instruments (the Sanctuary and Joyful Noise designs,) re-branded versions of Moog instruments designed and programmed to appeal to more traditional church markets.
This was recently serviced (November '22) by 'SynthPro' Jareth Lackey. (invoice for works carried out included) and also now includes a modern, bespoke internal powersupply from 'Synthtaste' for added reliability.
Everything works as it should, pots and switches are all behaving perfectly.
The cabinetry is in stunning condition, it really is a synth to behold.
A short video is attached which Jareth recorded after repairs were carried out."
