It could use some improvement - the board isn't well supported so dropping the pedal could break the tube. Here's the layout file if you want to play with it. Poor planning, needs more work, but since the build runs I just jammed in a box up-side-down instead. The original plan was to board-mount the level and gain pots with the tube facing down and the DC jack above it, but I tried and it didn't fit. The top-side has 3 jumpers, plus one on the daughter board. That is to say, a double-sided board isn't necessary, it's just for mechanical strength.

I made a double-sided board so I could effectively solder wires and the daughter-board underneath, but of course there are no vias, so they still needed to be soldered to the underside. I wanted to see if I could squeeze it in to a 125B, so I made a layout using ExpressPCB Plus and etched the board. Well, if you don't mind a 1590BB there's this.

(I got a nine-plug DC splitter tree but am using only two or three.) Doesn't seem to cause any added noise or other problems.This is an open community for the do-it-yourself pedal builders of reddit!

I don't always use my Cry Baby wah-wah, but when I do, I power it with one of the DC splitter cable lines. So whether or not you need a single big PS might depend on the number of pedals on your board and how much juice they each draw. (I affixed an AC power strip to the back of my pedal board, for the PS's and AC-powered effects.)

Of the other two pedals, one is battery powered (custom termolo, a 3V coin battery lasts years but tradeoff is no on/off indicator LED) the other is AC plug-in (1970s EH PolyPhase). To use a bigger 'brick' type multi-pedal supply, I'd have to make room on the board and it's seems like too much for just three pedals, and it would at this point only be replacing two wall warts. I was using a single beefy wall wart for all three, but the digital reverb was a little noisy so I put it on its own wall wart and no problem. I only have five pedals on my board (plus my separate spring reverb which sits next to the board), and only three are powered by DC wires.
