This is an interesting one. Huge range of sounds, and I like a lot of them. This one is going to hang out on the pedal board for a while.

The interesting part is that dialing a particular sound is not that intuitive. Lots of knob tweaking and head scratching.

I took a shot at matching the j201s to the specs listed in the build doc, but I'm not sure how much that matters.

I think i need to match the Jfets. There is some underbiasing then over biasing and then again underbiasing going on. Like it very much though

I read your post about it when I was trying to figure this out. There are definitely some weird sounds at certain bias knob settings. I tried changing pedal order after reading your comment about that. Putting the 900 after my tuner with a buffer seemed to limit a weird note decay sound I didn't like.
 
Do you take any extra steps to get the insulation on that hookup wire right up to the solder point? Maybe my skills are weak. I feel I like I need some space to avoid deforming it or melting it. I could see maybe creating the joint with it farther away, an then sliding the wire up close. Maybe my wire is just shitty.

No real surprising trick to it, just getting in and out as fast as I can. It's regular cheapo PVC wire. It definitely melts pretty easy.

High temp (750f) and good contact help with the speed. I do add a little dot of solder to the iron tip before I start the joint to help with the transfer.

Pressure might be part of that heat transfer equation too. I wire the switch lugs inside the enclosure where I can push a little with the iron. I know some folks do a lot of their wiring on the bench or holding things with a third-hand thing. If the switch moves when you push on it, and you're making light contact with the iron it'll probably heat a little slower.
 
The original Polivoks has similar knobs. They're kinda offputting when you see by themselves, but on a build like this, that has this factory machinery remote control unit vibe to it (your tag does a lot of heavy lifting on that)!, they add a lot of character! <3
