After an 18 month hiatus from building, i decided to jump head first into the deep end with this build. I’ve literally wanted to build this since i built my first pedal a little over 3 years ago but didn’t feel confident enough at the time.

I took my time with this one. I knew massive troubleshooting would be a hassle so before i did anything i double and triple checked everything. Had to pause a couple of times to check the forums to relearn some things i had previously forgotten.

I also learned from past mistakes and tested each pcb with my test board before doing the off board wiring.

There were a few minor errors. I wish i had placed the decal slighly higher on the enclosure to give me more space at the bottom for the footswitches. I had wanted then evenly spaced, but that screw hole in the middle of the enclosure made that impossible.

I could have also made a little more space between pcbs. It worked fine when i tested the spacing, but once i added the plastic pot covers , i really had to squeeze it to get in. I probably could have made up another enclosure, but i had already ruined one on a previous attempt and wasn’t about to reapply the over the top decals on all sides of the enclosure. So, for now I’ll just be happy with the result.

I remember reading somewhere a couple of years ago on these forums that these pcbs can be noisy and ordered shielded wire that has literally sat on my desk for two years. I hate working with it and probably could have cut it shorter for space management but again, it was something i could live with.

The best part is that all 3 worked the first time i fired it up. I was so paranoid that i was going to break something while trying to cram everything into this box.

I’m not sure what possessed me to decal the sides the way i did. Not sure its a hassle I will ever do again, but I’m glad i did. Reminds me of Zubaz and i like it.

I’m too tired to go see what all i can make this thing do today, but can’t wait to see what i can do with this thing and figure out where on my board its going to go. IMG_0635.jpeg IMG_0626.jpeg IMG_0625.jpeg IMG_0638.jpeg IMG_0637.jpeg IMG_0639.jpeg IMG_0640.jpeg
 
Nice. I've had essentially the same project sitting on my desk for two years but I don't have the motivation to build it. Mine would have PPCB smart relay bypass switching, if I put it together as intended.

The Cerberus idea is clever. I like the overall aesthetic you've got going on.

I really thought about including the Smart relay bypass into it once I started building it and but ultimately decided I didn't to wait on ordering something else.
 
had a leftover I/O faceplate huh
(it's a killer build overall but that aspect ruins it for me)

I really debated on using that. It wasn’t in my original plan. I really dislike asymmetrical things and as i was finishing the project i realized i wouldn’t be able to center the DC jack. (I just realized in my effort to avoid asymmetry in one way, i made it asymmetrical in a different way…) And in my ‘I’ve been working on this for hours and am mentally shot stage’ I used the faceplate.

In retrospect, its my least favorite part if the build. I have a backup 1590DD and thought about doing another pass at it that would fix all the minor issues i don’t quite like like the spacing between pcbs and the footswitch spacing (queue my hate of asymmetry) but as its just going to be for me and i’ll never see it once its on my board, i’m willing to bet its just one of those things i want to do but won’t get around to for a while.

Zubaz! Nice job. I did almost the same build (except with the smart relay switching) and mine is a tad noisy so I may go back and try shielded cable.

Do you have a build report of that? I want to see how the smart relay switching fits inside the box.

Thanks. Is that a 1590XX enclosure? If so, that may be the thing that would motivate me to rebox this so that I can have my switched aligned.
