Hey. New on the board and not sure if anyone is still on this thread at all but figured I'd check. Currently putting a chasm together (super excited to get playing on it) and just thought I'd see if anyone has a wiring diagram. I'm sure I'll figure it out just seeing if could save myself a little headache as I always seem to mess something up while wiring. Thanks!

[deadastronaut]

Hi, yes were still alive..

there is a pdf on my site with switch wiring...

Look below ...

Thanks rob! Can I be needy (I'm obviously a novice at this) and ask to see if you or anyone else out there has a diagram or detailed gut shot of the full wiring including jacks and power? Sorry to be a pain in the butt. Thanks!

I just finished building my chasm reverb and it worked for about 5 minutes then all of a sudden it started making this really loud, distorted noise that was so loud I had to turn the amp off. Any ideas on why this might be happening?

[deadastronaut]

Check your 5v reg is around the right way...

voltages, and pictures will help.

Yep thought so,  flip that reg around...

the 7805 is opposite to a 78l05. 

edit:hopefully you haven't damaged the brick...fingers crossed

[gcol]

shit :/
I flipped it round and the light still comes on but sounds the same, just like a really overloaded sound that increases when I turn the volume pot up. Sound doesn't change when I turn up any of the other pots though...

[deadastronaut]

hmmmm....shit indeed. 

basically you have fed 9v into a 5v brick...oops!!!. not good..

do you have 5v going to brick pin 1 now then?.

[gcol]

Yea I pulled out the REG1 and soldered it back in the right way but worried I might have fried the brick
