I designed with the help of Simon Cox a PCB to fix the hum problem of the THC SY-1 Syncussion, which also helps in the SY-1M in case you have a coil hiss.
A Syncussion Dust Cover is available too, this fits for the SY-1 THC Version and SY-1M Version.
Futhermore my Webshop https://www.DIYSYNTH.de is back, all new products are exclusively available there.
