Very happy with this device overall. Good "upgrade" from GT-8. I own the ZOOM G3Xn as well and prefer the BOSS GT-1. It's missing some tiny things which could have easily been added, but otherwise it sounds great, is very light and does the job! For those who this might help: the GT-8 has an "active range" setting on the assigns. The GT-1 is missing that, so your assigns work across the full range of the pedal only. The GT-100 has this so it was obviously omitted in the GT-1 intentionally.
