The VC is still great! My worries that fixing the tuner would break the VC were unfounded. It still sounds wonky with cleans, with no way to adjust the doubling/chorus/tremolo-like effect out of the sound, but for anything slightly overdriven to high gain, it’s wonderful. Still very low latency even up to 5 half steps down (maybe more, I didn’t test further).
I tried playing with the settings to get the clean sound not sounding so wonky, and anything but “fast” made it less warbly, but added other artifacts. So it still should only be used on clean tones in a full-band context. Not recommended for crystal clean arpeggiated chords.
As far as latency, it doesn’t feel any different so I didn’t run further tests. I may at some point.
