Before catching fire they get this really nice red glow happening

I lost the 15V zener that was regulating power to the EQ board in my bass amp once. In that case a very very hot signal had fried all...

The pots we can see look as if they are insulated on the back with electrical tape. If that is the case that may well be your problem...

With these, the trick is usually to look from the end. One side will be straight up and down (or close to). The other side will be a...

Photos of the solder side will probably help. Given that one side is working, your power is probably working, unless there is a...

I am not sure if this matters or not, but the only difference I can see that is in the audio path that is common to all the octaves is...

90% of the time if a pedal works out of the box and doesn't when it's in the box, it is either bad offboard wiring, or something...

I think that in your situation before I replaced anything more I would trace through with an audio probe just to see what happens to the...

The photo isn't clear. I am a bit sus of the soldering on the transistors, but it is hard to tell. What voltages are you getting on...

What behaviour are you seeing from the gain control? The gain on this does 2 things. It increases the gain (which should introduce...

If you have 2 identical resistors to make up a voltage divider, and the divider is not giving you half voltage then there is a lot more...

There are a couple of tantalum caps on the board. If they are C5 and C6 then they are polarised - tantalum caps are definitely polarised.

I am guessing the capacitor doesn't fit. It looks as if the leads are not touching anything they shouldn't, but you are just asking for...

The numbering of the pins in that picture is the standard numbering used by every manufacturer and every engineer in the entire world...

OK. IC1 pin 4 should be ground - this is correct IC1 power pin (8) should be at 9V (or close to). At 0.3V this is way wrong. You are...
