HI! I recently modified my SD-1 to fulldrive mod. I love how the pedal sounded. Now the problem is my pedal is having switching problems. I traced the problem with the D1, which is the diode that switches the effect on. I was able to change the diode and will work perfectly for about a few minutes and then die again on me after 3 to 5 minutes of use. It seems that there could be over current running in the diode, but I don't know how to trace the problem. Tracing the circuit from slot 13 (from the power source) it goes thru R30, D2, D7, and R18. Which could be the culprit? Thanks!

Just to update, the significant lines it goes thru are D2, D7, R18. R30 would be related to the LED.
