It rubs off easy

Is the red a liquid out of the capacitor? And therefor a died capacitor?

Zener?

Log =lug haha Forgot to mention bypassed signal works. Are the two jfets working as a flip flop? So one is open the other closed? Edit: Yes flip flop. I surprise myself understanding a little bit more than I thought: http://www.geofex.com/article_folders/tstech/tsxtech.gif

Schematic is not right. The burned 100u has no number en the c20 is c21 on the board. I dont understand how I can measure 5,6 volt on all three lugs of the level pot. The pot itself measures 85 k on the outside logs and middle log measures 85k maxed out both settings. So the potential on all...

Not sure why it burned. Not my pedal. Wrong power supply is my guess. But I am not sure. It is my first real attempt troubleshooting and it is gonna take some time. Thats ok. I use the schematic and try to follow the traces. I measure 8.95 volt and around 5,6 volt??? after the voltage divider...

What can I do to have a bit more lowend on this pedal?

Signal is gone at the junction R23 R24 engaged and disengaged.

OK so far: I think the power section is a little bit different from the schematic. C22 is 100uF on the board for example. I think in the schematic the 2 opamps are other way round. I have the clipping diodes on 6 and 7 of the IC. A lot of signal on the first opamp and after the non inverting...

D1and C20 where burned. I just replaced them.

Later this afternoon I'll post some pictures of the board and measure some voltages

i am using the TH audio probe in my first attempt to search a defect. I changed a burned diode and Capacitor at the power section. With the probe I am loosing the signal at R23. Is at as simpel as replacing that or am I missing something in understanding why I it is possible to loose signal at...

I like this. Gonna give it a try. A friend of mine has a laser cutter, so I am also considering engraving a pickguard plate.

How do you think this compares to the golden Falk.

I see your point.

@HamishR Mmm but how can you see the pointerknobs position?

The green Ringer is a classic. Never leaves my board. Just a foot switch and thats it.

A tubescreamer in front of a Rat is commonly used. How do use the OS2?

I had this pedal in 92 with my ac30.
