I bought this pedal in order to mitigate the want/need to try out an 8-string guitar, as this is much more affordable and is easily the best-sounding polyphonic pitch shifter pedal on the market, out of all the videos i have watched on Youtube.
I also wanted to use to emulate a bass guitar, as that is also costly and takes up room i don't necessarily have.
I just got it and tried it out and i quite like it! The tracking is very smooth and responsive, although i do hear more artifacts when playing chords then i did on the reviews i watched online, but it happens more with chords that are dissonant or out of tune.
I noticed that when i hear the acoustic string noise of my guitar while playing with the drop tuning on, it can sound pretty weird, but the human ear is that sensitive that even when the faintest sound is out of tune we definitely hear it. Playing louder or through headphones eliminates this problems of course!
I'm just disappointed that there are more artifacts the lower the note being played, both by shifting the pitch further down and by playing lower notes on the guitar even as less drastic settings.
