Thanks. I tried using fast with tracking at zero, set low cut to 190Hz and high cut to 7khz to see if that would improve things. The results are the same or worse for me. I've uploaded the clip (AXE-FX is first, NDSP second). Uploaded the stems and DI as well.
I think fast with a speed of 0 is probably going to have the most artifacts. Smooth and speed of 10 sounds better in this particular instance, but it still exhibits a "wobble" sound in comparison to the NDSP algo.
