This one was sold labeled "not working".
Very low output in both on/off states.
Pedal has buffered bypass and stupid ass 3pdt wiring, which contributed to overall mess. Add very thin traces, stupid and unreasonable routing = very difficult to locate a fault, which took me a couple of hours. Could have been easier if walrus decided to use wider traces and green solder mask.
Also, flux residue smells like a partially burned crackwhore. I nearly died.
As a result, 2 dead jfets (5458 smd) and torn pad under output cap. Had to practice gluing/restoring pads /w some copper foil (salvaged from a piece of copper clad) and thermal adhesive.
Overall pretty decent delay and nice tap tempo. Low noise level thanks to compander.
Sadly, have to return it back to the owner.
