So I just received my 2nd HX effects. The first I sent back because of noise issues. My hope, in this unit vs pedals, was to eliminate background hum.. not so much it ended up being louder than my old pedals. I tried so many combinations to reduce noise floor- different guitars, using amp vs just line in on mixer, different global settings, factory reinstall, update.
My base test is when hx is on but all effects off vs putting it in true bypass. Noticeable increase in background noise when not in bypass. Differnt degrees of noise if effects engaged. Hook it up to computer via USB it gets worse. Unplugged computer to just run on batteries.. still there. Tried many things then saw others having this issue so I returned it and got another. Same deal with the replacement. Serial numbers close on both units I've tried. ill try one more exchange. Must be a batch of lemons. Watch out with buying this as an open boxed item. I think they're just sending them out and hoping younger players won't be critical.
The HX should be quieter that my old pedals.
Others having this issue feel free to chim in.
