The pedalpcb board for this one is tight - use 5mm resistors if you have them, else you'll be standing them on end. The JFETS require a mounting board as the pcb doesnt have a surface mount option. I had a batch of JFETS I'd graded for the Chop Shop build so was able to find two matched pairs for this.

The mods to change from basic BD-2 to Waza version are in the table at the bottom of this post. Thanks Chuck D. Bones!

Build was uneventful apart from having to combine a few resistors to get specific values. I had to sub in 2 68nF caps for 2 56nF caps I didnt have, but it sounds good so I got away with it.

The drive is rich and deep. Very interesting texture. No fizziness that I can hear. Tone covers perfect range for me. Gain is more than enough. Closest pedal I have is my Gainster clone (and that's a good thing).

Looking at the images I guess I need a better method for removing flux than a toothbrush and alcohol spray...
