Background:
- I put the entire pedal together but soon after realized that I had two resistors in the wrong place. While un-soldering the components, I managed to mangle and destroy the switch and power jack (where the 9V power supply plugs in to). I bought a new AC adapter power jack from radioshack (see figure 1 below, I'm almost positive it is the correct size, but I just ordered a few from BYOC... should be here by the end of the week) and two new switches online. The switches that I ordered, (to the best of my knowledge) are the correct single pull, double throw switches. Re-soldered everything together, re-flowed all the solder joints... I put it all together again and no luck!

When the amp is ON, guitar is plugged in and the pedal is NOT on (or plugged in to power), I get a perfectly good signal (I'm assuming that means the "true-bypass" is working/wired correctly)

When I plug the pedal's power supply in (while the amp is ON), I get a loud hum. This goes away after about 10 seconds. (I think this may be from the metal power jack causing a ground short?)

After the hum goes away, i test each position of the trim pot. They all allow a signal through, but the volume is very low (even with the potentiometer turned all the way up.

And most importantly, the LED does not work in any of the positions

The images could not be uploaded for some reason (I checked file size, but still... ?). So here they are...

Any comments/guidance is greatly appreciated!

Which Rat Shack jack (part #) did you use?

Looks like the metal power jack barrel may not be completely insulated....?
I usually ream the hole in the case out enough to use a rubber grommet...or did you.....I can't tell....

I'm still searching for the part number for the Radioshack plug. I get some new plastic ones in on Thursday this week so I'll know if that is the problem then.


No insulation on the existing jack.

I replaced the power jack with one I ordered from BYOC. The hum is gone, but the pedal still doesn't work.

"doesn't work" -> True bypass works. No signal when the pedal is on (with volume knob appropriately turned). No LED functionality.

I get a very low signal when the boost is ON, in the germanium setting, and the treble/mid switch is far left OR far right. No sound when in the middle position.

One lead lead wire from the board to the 100k pot is short on insulation..... looks dangerously close to another solder connection. That kind of thing can haunt you.......been there

In the picture above, to the left of the rotary switch, is there a solder bridge? Double check that and for any other solder bridges. Also, are you 100% sure you set up the rotary switch propery, per the instructions?

Beyond that, do you have a signal tester?
