I'm wondering if anyone else feels that the Octoverb effect doesn't sound great? I feel like the note gets out of tune, then slowly gets in tune. I guess it could be a cool effect if you wanted a sort of vibrato meets verb sound, but I love the idea of having the Octo-verb sound more like a shimmer. I owned the M9 and the Octoverb in that unit sounded much better than the Helix. Any thoughts or help is great.
