Great looking pedal Thanal9999! Is that hand painted artwork? It is hard for me to see if you etched the design in first.

I guess I should post a pic of how my pedal turned out. I have posted gut shots in another thread. I followed on with the theme of the father of the Chasm Reverb, but I stuck to a black on white color scheme. The knobs are aluminum. The odd gold color and the gold shadows are from the crappy flash on my quick and dirty camera.

Looks great man, very nice, love the gold knobs on white, classy...

Oops..they are silver...sorry, my crappy phone...

Thank you...! Yes it is painted by hand... it isn't actually what I wanted it to look in the first place but it was a first time try for painting a pedal...

Now that you mention it, the "gold" knobs on the white pedal do look nice. I will have to look around for some to try out. I would still be stuck with the silver stomp switch button.

yep, and jacks too...looks cool as it is.

Been working on something. I like this box of tricks, I just don't like the wiring.

I wound up doing a fair bit of wiring on the back

but it works now

Once I got the board working, it was the easiest build I've done yet in terms of boxing it up, since the stomp was already in the circuit

just wire the jacks and power!

(Out of respect for Rob, I won't be sharing the pcb at this point in time.)

I DEMAND that you disrespect Rob and share that with me!

Out of respect for Rob.....

You need to add about 12 more LEDs to that build!

Out of respect for Rob, you should jam a burnt weenie inside the enclosure.

deadastronaut · January 01, 2014, 07:32:10 AM

Lol....

@alan. Cool, glad you got it sorted man...

excellent etch too

Finished up my build of 2 units this morning. Both turned out great and sound great, too! No idea what I'll do with the extra but it may come in handy for trade bait or something. I used a couple of blem housings I had lying around and added a momentary footswitch for the oscillation.

deadastronaut · January 02, 2014, 06:52:48 AM

nice build ron, the gap between the switches gives an ideal space for the brick too..

Thanks, Rob. I'd normally put the battery there but I figured this probably isn't too battery friendly. Thanks again for the pcbs!

Help!!!

>@john D : latching dpdt .not momentary (you knew that ) ...ALPHA is nice..

I finally built this sucker and it only works if I hold the latching switch down continuously. When I click it, the LED only lights for a spilt second and I get no effect. I only get clean signal. Suggestions? Bad switch?

deadastronaut · January 05, 2014, 03:08:09 PM

that's weird..yes i suspect the switch is shot...

have you another one?..if not wire up a dpdt toggle just to test.

Are you sure it's a standard footswitch and not a momentary?

Jdansti · January 05, 2014, 04:20:56 PM

Thanks, guys. I just checked the resistance across the switch terminals with it still wired up and the power off, and it's acting like a momentary switch. I had ordered a latching switch, and it clicks like a latching switch, but it must not be latching.

Here are my readings:

Side note: the 5k and 12k readings flip flop when I change the meter lead polarity. Probably due to the diodes in the circuit.

I can't find another DPDT stomp switch in my stuff, but I've got some 3PDTs. I'll try one of those and see how it does. The 3PDT footprint isn't any larger than the DPDT given the DPDT's X-wing terminal configuration.

Jdansti · January 05, 2014, 07:35:07 PM

Thanks for the help. I swapped the switch with a 3PDT and that took care of the bypass problem. All is working now except I get no oscillation. I checked the SPDT osc switch and it is good. I checked the connections to the switch and they're good. I checked the locations of the switch connections to the PCB and they're correct. I'll take a look at the schematic and see if I can figure out where to check next.
