Ordered a Carparelli / M5 / ZXK (the same, rebranded) wireless system last month; there was an excellent sale via AE. It finally arrived last night. first impressions: sounds crisper (in a good way) and more detailed than a 2m HOSA cable. range is good, I haven't tried going further than the other end of the house, no dropouts. hinge is snug tight, so it stays put regardless of how it's folded. noise seems non-existent. ran it into a digital pedal with heavy gain, still no noise. i've got 'em set to CH2, as I figure 99% of people will leave it on default CH1. the Rx & Tx look identical, I'll get a sticker to put on the Rx side. obviously, the plug's neck is long enough to go deep into a recessed tele jack! unexpected side effect - the clarity has made me excited about the middle position mix. [edit, added] most importantly, it doesn't load the pickups like the Aroma ARG-05 did.
