Title: Firebomb Troubleshooting - where to begin?
Post by: camsna on December 12, 2010, 01:13:17 PM
So - my build is done and I have a few problems. They are:

1 - Neither LED lights
2 - When the 2nd SHO is engaged, there is no volume unless the volume (middle) pot is turned all the way up

Gut shots may come about eventually, I just won't have time to snap any until the end of the week. So, hopefully we can brainstorm without them ;)

Thanks again!

LED doesn't light means either the LED needs to be reversed, or it is not wired properly to the switch.

Not sure about #2. Does the second one work if the first one is off?

Yes. #2 does work - as long as the volume is dimed.

I'll check the LEDs direction. I triple-checked them before putting them in, but I may have still gotten it wrong.

Thanks!

Forgot to update, sorry 'bout that!

1 - LEDs were in backwards. Derp. Thought the square pad denoted + lead. Boy was I wrong.
2 - Fixed a couple of solder joints that I think were causing partial shorts.
3 - Pedal is (now) built and works perfectly. On its way to my little brother for Christmas!

Thanks for the help!!!
