My problem with (bufferless) YATS is tone pots. Must be W-Taper. And then Mr Wiltshire came to rescue. Or we can build scaled version if we dont have exact pots.
small size DIY? Perf-ing CrapFi delay. Easy, low part and can be pt2399 tester. Madbean cave dweller also candidate.

Had fun with Bentfishbowl Boot Boost and Boot Fuzz, FSFX (Fleeting Spider) Quiet Treble Boost.
Measure twice or more before execute. That the fun and joy moment.
