I’ve build a swha kit bought from muzikding and I really love how it sounds. But I don’t understand why spdt is noisy like this. In the first link I only play and in the second I active and desactivate spdt switch.
If it’s a pop when you switch it on and off firstly check R2 has good connection by reflowing the solder joints then try soldering a wire from 3PDT lug 1 (input) to lug 6 as below to ground the input when switched
Ok I was THE problem…C6 was not able to do his Job because (i don’t know how…) + & – were soldered …
I kill a led and pcb look like a battleground… but I’m happy to say that Learning electronics without theories haha It may be sometimes hard 😀
