No build docs, no worries. Everything you need is on the pcb. Tight fit in a Gorva. I am waiting for the 2n5457s to arrive in the meantime I put a set of J201s in and it sounds great. Has a lot of tweak-ability with the three internal trims: treble, bass, and Boost. And the mid and gain knobs have a lot of range.

After being able to turn up to decent volume on the amp, I can say with out a doubt this build is not leaving my board anytime soon. It does that magical thing to the sound that up until now I have only heard from pedals that have transformers in them. This has no transformers! Wow, component wizardry, no wonder they are asking $300+ for the real deal.
 
Ok, I just realized that not only is the artwork on the real pedal a doctor dropping lsd tabs in the drinks, and the Beatles song Dr. Robert is about their drug dealing Dr.
I spent way too much time listening to the doors in my youth to realize the Beatles were on the stuff too…

The artwork on the "real" pedal is by Klaus Voormann, friend of the Beatles from their Hamburg days, illustrator of the Revolver album cover, and musical collaborator with all 4 ex-Beatles. Very interesting and talented bloke in his own right, and the absolute perfect person for the job of doing the pedal art.

He also played Bass on the Carol King Tapestry album, I think…
 
I forgot to mention that had one substitution. Even though I had an A25k pot on my Tayda order it wasn’t in the bag, first time missing a part, I used a A100k pot instead. Not sure what if anything I’m missing out on. There seems to be a huge range of sounds from 0-10 across that pot (mids). I also noticed when the mids pot gets around 7 it starts adding in some more break up to the signal. Not sure if that happens with the correct 25k value or not. No plans to swap it out as I love it the way it is. Just wanted to share. 38D23BF3-D575-48CA-973F-77DCE1534219.jpeg

That mid pot increase adding to the break up is common behavior for that pedal and amp
 
If you don't mind me asking, did you happen to go for specific spec on your transistors? Just built this and whilst it sounds good it's very low gain. The boost side is dirty and loud as hell, but the regular side is quite subtle.

Have you tweaked the trim pots? The boost one specifically?

Also, the MID pot affects breakup too. If you get past 7 on the MID pot it should add to the gain. Maybe try another set of transistors if you socketed as well.
