Hi Guys. I hope someone of you can help me. I built a GSSL with two SuperSidechains (PCB grinder) and a turbo board (ExpatAudio), but it doesn't work yet. Without the modifications, the compressor works perfectly. After I installed the modifications and nothing worked, I sent the compressor to Markus Samper (greetings go out). He said that the two side chains and the turbo board were working properly, but he didn't have time to check the cabling and said that the fault must be in the cabling. For the cabling, I used the Don-Audio sketch ( because I have the same equipment (British push buttons etc.). The left push button (compressor) should be the bypass button, so when pressed, the button lights up and the compressor works. The right push button switches the turbo mode on when the button is pressed. Furthermore, I once read in an older post here in the forum that only one relay has to be installed on the SideChainBoards for this circuit. Is that true because I installed the relay on each SC-board???? Here are two more sketches of my current wiring. I hope someone can help me. Best regards: Fritz

Welcome to the forum!
Turbo plus 2xSSC ? A bit tricky. Please use the dedicated 'GSSL add-on help thread'.
A good idea is to add only one modification at a time instead of three and even four when also counting the BYP switch. And I'm afraid you'll have to do a bit of reading  ;)
