D3lay and Threeverb combo build with single footswitch bypass and momentary sustain

Hey all,
I’ve wanted to put together a reverb and delay combo pedal for a bit, but I wanted them to run off a single footswitch in series (delay into reverb). I worked out my expected wiring and confirmed with @PedalPCB to make sure I had it dialed in. Put it together today and loved the results (thank you Pythagoras). I knew I wanted to add a little sustain functionality or something else fun, so after a suggestion from @zgrav to feed the output back into the input, I came up with the delay and reverb out being fed back into the delay input for feedback mayhem.
I’m including an image below that explains the wiring routing in case anyone wants to build something similar.
Here’s what it looks like on the outside:

Here’s what it looks like on the inside:

Here’s what it sounds like:
And here’s the wiring:

Oh and it’s worth noting, if you’re doing two circuits in series like this off one footswitch, you attach the SW pad and GND pad from whichever board you want to handle the LED. The other board doesn’t need anything in those pads or in the LED pads.
 
If anyone has any ideas to debounce the momentary switch, I’d love to hear them. Obviously there is room in the enclosure to do more mods and such, so if anyone wants me to try anything else just for the hell of it, let me know.
 
Well what can I say

Dan's the man?

Cheesy but true

Absolutely excellent I'm really loving the logo too

I'll need to start bookmarking your posts now Dan your build reports are always top notch

I think Mr @PedalPCB should be giving you a wee bit of commission, everytime I watch your vids I think I'm buying that!

I'm gonna save up and go get myself a ski mask! covid wages ain't that great so got to get the funds some how!

Thank you sir! And you’ll love this... after finishing the second Pythagoras board I realized I accidentally installed an SPDT on-on instead of on-off-on and had to spend almost as much time trying to remove that damn thing as it took to populate the rest of the board. All because I had accidentally put the on-on in the wrong drawer. Needless to say, I’m double checking the side labeling of my switches from here on out!

I was going to recommend a dual FV-1 Pythagoras (Pythagori?) board to @PedalPCB just for the purposes of doing effects like this, but with the Terrarium coming it doesn’t seem like it’s going to be necessary. Either way, if people are bored of the standard FV-1 stuff or the delay and reverb options try something like this! Or don’t bother with FV-1 and do a Magnetron in series into a Spirit Box. Or an always on Amentum Boost into a Super ‘64.

Here's what I do with onboard components fwiw, think the tip came from @Cybercow

I tack solder, for want of a better word, onto the very tips of the pot / switch lugs with a little solder

Then stick it on my test box if it all works I just use my solder sucker to remove the wee bit of solder and fit them properly, it's a lot easier to desolder and less likely you'll pull a pad off anything for debugging or whatever
 
This is a great combo and giving away the wiring is the best part of it!

Thanks a lot and congrats for another first class build!

And yes Terrarium will possibly be the next logical step I think. :)

This is probably something I should be doing anyways, since I've had to swap out bad 3PDTs in the past (thanks Tayda). I've seen some people just tack those regardless to prevent the epoxy from melting, and maybe flooding them isn't entirely necessary regardless.

Sharing the wiring is the fun part! I'm sure others have wanted to do dual pedals off a single footswitch, so if they hadn't sorted it, hopefully this helps.
 
I think one footswitch works particularly well here, as you have blend and volume control for each side.
Most definitely. The mix knobs make it easy to blend however much you want of either. What I have noticed is that there is a very delicate balance between the volume out of the delay and the trim pot setting for the momentary feedback. It would probably be easier to move the momentary trim pot to an actual dedicated pot so it would be easier to adjust. I may end up doing this.
 
My playing is pretty straight forward and probably would be considered dull by many, but I think I could get into something like that

I am not a lead guy by any means. I’ve always liked weird texture-y stuff. So big cavernous effects excite me.
