PedalPCB ADHD Overdrive (Fulltone OCD 2.0) and bypass

OD is Glorious

My 21st build.
Thank you to @Hetari Gotoh for giving me ideas and a template. I socketed a few components and that seems to work very well. Hetari Gotoh also spoke of a whine and the need for isolated power with the daughterboard. I think that is correct and you can see an example in the video. I did not use Hetari's idea of using an A1M in place of the 500. The pedal very responsive the way it is designed. So what is different in this build? I had no problems whatsoever in this build. When I completed the motherboard I put it ion the PedalPCB AP and it was amazing. In light of that sound I decided to get the daughterboard installed and substitute two of the transistors that I did not have. For the motherboard I did not have a TL082 so I used a TL072 until I order the correct IC. For the bypass daughterboard I used J201s in place of the 2N5457s because I had to order them. Pay attention to components here on the daughterboard - I put the electrolytic caps under the board as Hetari did in their build reportand I needed to bend the legs for the transistors.

How many ways do I love this pedal? Let me count the ways: klon like transparency, Plexi like tone, Timmy like tone control, TS-808 like mids, OCD Ge like crunch and gain. The Guardians of the Analog is going to hate that I used these non-proletariat diodes... but the plans called for Ge diodes and I had some super duper !N34 diodes. Normally I am not digging the Ge diodes but I am sold on this circuit. As I have previously said in this forum I loved to be able to get out of the treble and hump. There is a place for that and this pedal can go there too if you want.

For the Improved Bypass Module of course I needed to order the two 2N5457. In the mean time I read the forum and opted to install J201s. So take that and the different IC into account when reading this report. I went with the powder coated case, a thermal ink label, PedalPCB top jack plate, switchcraft jacks, and a 1kg footswitch.

Do yourself a favor and build one. If you do not want the bypass board, no worries because the ADHD was glorious on the PedalPCB platform without it. I know what I like in overdrives and you can see I sort of collect them.

Here are some images of the journey. For soldering the pots i drilled a second enclosure for a Maximum overdrive and that way I was able to mount the board and pots on the outside of the Maximum enclosure for soldering.. (the toggle is on the opposite side for the Maximum.

And a video. This is an American Standard Stratocaster through a 1964 Vibroverb.

Edit: added an image with the red toggle cover for the mini switch

Well, I got the correct transistors in this thing. Pedal still sounds glorious. Really a fantastic pedal. I don’t know who designed it but thumbs up.
