I recently got a fully functional hammond M3 organ. I'm new to organs and was messing around with it. I saw a video of someone pitch bending it by toggling the start switch while it was running to change the speed of the tone generator to bend its pitch. It worked a couple times then it lost almost all its volume. You can still hear some sound (sounds kinda buzzy) from the lower and upper manual but nothing from the foot pedals. Its very quiet now. The tone wheel and starter are working well still and the tubes still have the same glow as before. Does anyone have an idea of what broke? Thanks!
