Forty years old.
Tuned like it’s Tuesday.
A Kreuzberg workshop for vintage analog synthesizers. We restore Moog, Roland, Korg and ARP component by component, and sell them with a full twelve-month warranty. Bring us yours, too. We’ll find the crackle.
Drag a knob up or down, scroll it, or use the arrow keys.
On the bench most weeks:Minimoog Model D, Juno-60, MS-20, ARP Odyssey, Polysix, SH-101, Jupiter-8, ARP 2600, Prophet-5 and Korg Mono/Poly.
Five stages. No shortcuts in the signal path.
Every instrument goes through the same chain, whether it’s a €400 SH-101 or a Jupiter-8. We log each step (measurements, replaced parts, before-and-after scope captures) and the logbook ships with the synth.
-
Stage 1
Intake & diagnosis
We power it up on an isolation transformer, listen, measure and photograph everything before a single screw turns.
- Rail voltages & ripple
- Oscillator drift test
- Written estimate
About 2 hours
-
Stage 2
Teardown & deep clean
Boards out, keybed out. Every pot and slider is cleaned and lubricated, not just sprayed. Cases are washed by hand.
- Pots & sliders serviced
- Contacts re-tinned
- Wood cheeks oiled
About 6 hours
-
Stage 3
Component work
Electrolytics recapped, tired trimmers replaced, keybed bushings renewed. Original ICs kept wherever they still sing.
- Full recap (where due)
- Battery & leak repair
- Original parts bagged
About 8 hours
-
Stage 4
Calibration
Factory service manual on the bench, frequency counter in hand. 1V/oct scaling across eight octaves, filter tracking, envelopes.
- Scaling to ±0.5 cent
- Filter & VCA trim
- Voice matching (poly)
About 4 hours
-
Stage 5
72-hour burn-in
It stays switched on for three days in a warm room, then we recheck tuning cold. If it drifts, it goes back to stage four.
- Thermal cycling
- Final play-test
- Logbook signed
72 hours
“A good restoration is invisible. You shouldn’t hear our work. You should hear the instrument the way it left the factory in 1979, minus the hum.”

Garantieschein
12months
Parts, labour, and the drive across town.
If anything we touched fails within a year, we fix it, free, with no arguing about what counts. Inside Berlin we’ll even collect it from your studio.
Buying vintage shouldn’t feel like a gamble.
Originality over “upgrades”.
No mystery mods, no swapped filters. If a part has to go, the original is bagged, labelled and returned with the instrument.
A logbook, not a promise.
Every synth leaves with a printed restoration log: what we measured, what we replaced, and scope captures before and after.
Specialists, not generalists.
We only work on analog synthesizers. Since 2011, four technicians with a bench each have restored 1,148 instruments here. Between them: 60 years at the bench, and a drawer of NOS parts most shops don’t have.
Play before you pay.
Every instrument is plugged in and waiting in the showroom. Book an hour, bring your headphones, take your time.
Bring it in. We’ll listen.
Drop off a repair, book a play session for an instrument in stock, or get a quote by sending us the symptoms first. We reply within one working day.
