XviveU2 Guitar Wireless System With Rechargeable 2.4Ghz Digital Guitar Transmitter And Receiver For Electric Guitar Bass Violin, Carbon, U2Cb

This device will not work with guitars using an active pickup (battery in the guitar). I tried this on 4 different guitars. First my Faith Jupiter electro-acoustic produced a high pitched buzz/whining noise. Then I tried it on an Alhambra nylon strung electro-acoustic. This was marginally better but the buzz was still there. The next guitar I tried was a Pinnacle Ovation electro-acoustic. The signal on this showed not only the buzzing but an almost complete breakup of the signal. Finally I tried a Fender Strat which of course has a passive pickup and on that it worked fine. So, I have returned the unit. The description by the seller does not mention this problem.

These things are a complete revelation. I use them on my semi-acoustic violin combined with a Roland Cube amp, and the rest of my band are sooooo jealous. I charge them up via USB every few practises, but other than that I am FREE from cables! It's so wonderful to be not tripping yourself or everyone up, and as we perform outside a lot and have to move between performance spots, it's a total revelation to not have trailing cables. Also I can move further from the band and do our own soundcheck while playing. I can't notice any difference sound-wise between using my lead and using these things, but we don't have a super hi-fi sound so that's not really a problem. Anyway, totally brilliant, well made, work well, and they came in a beautiful box which is a reassuring sign from the manufacturer. For the price they are a complete no-brainer, knowing what my band spend on their instruments. This combined with a £120 5-string semi-acoustic chinese eBay violin.. amazing. Don't hesitate.. just do it!

Some other reviewers have noted that this device doesn't work with their active pickups. The product packaging (but NOT the Amazon listing, tut tut) makes it clear that this MIGHT be a problem: "The U2 is suited for all electric string instruments with passive pickups. Performance with active pickups will vary depending on the type of pickup".My experience on that, for what it's worth, is positive. I've tried it with these active pickups: - Fishman Rare Earth soundhole humbucker (button battery) - Mimesis soundhole single coil (button) - B-Band A3T undersaddle (9v) factory-fitted in a Tanglewood acoustic guitar - Unknown brand 'ASE-N' (9v) factory-fitted in an Ozark tenor guitar - Fishman lsysT (?) (9v) factory-fitted in a Martin LX1E - Myers 'Feather' (button battery) and 'Clamp' (basically the same thing with two different mounts)It worked first time, every time, with all of them. The Myers ones were interesting because although Myers calls them 'pickups', they're actually little condenser microphones. This puts them outside the intended use, but they were just fine.I've also tried it with a slew of passive pickups including Seymour Duncan (humbucker) and K&K Twin (piezo discs, in a mandolin). You'd expect it to work well with them because it was designed for them. It did. It was specially nice on the Yamaha electric violin YEV-5 (passive), where cable drag can be a problem for the player.As far as I can tell, the sound quality is the same as with a cable. Of course, to test that, you've got to listen one way, then swap connectors and listen again. I don't know about you, but my ears have short memories. For what it's worth, it sounded the same to me. I'm reasonably fussy, your Coefficient of Fuss may vary.In the same way, volume level is the same as a cable. Same caveats apply.I tried it from two rooms away, say about twelve metres, through two concrete walls and a steel radiator. It worked. I tried it in the same room as my WiFi router. It worked.I've given it four rather than five stars because it seems a bit expensive for what it is - a cable replacement. I haven't gigged it yet. If it performs reliably at gigs where there are lots of magnetic fields and radio signals flying about, I'll put it up to six stars (© Nigel Tufnel) because then it will be worth its weight in gold. It weighs 41gms per unit, by the way. At today's UK gold price that would make the pair worth £113.57, so it's a pretty good gauge for once.

Out of the box these worked very well. Light in weight yet very good external build quality. Currently priced a lot better than the other (British made) brand I tried which failed after a few months and was returned under warranty.Walls don't seem to affect the range or signal (within reason) as I moved a good 20 metres away with 2 walls between me and my guitar and and the amplifier into which the receiver was connected with no problems whatsoever.No apparent latency or noise.The only possible fly in the ointment is that the rechargeable battery appears not to be user accessible so when it ultimately fails it cannot be replaced however I'll research this more and update as and when.... other than that highly recommended.Update 02/11/2018: I received confirmation from the seller that the internal battery is not user accessible.In addition I have noticed that there is a bit if a 'stutter' fairly often which interrupts the signal. Nothing major for bedroom use but could be a problem for stage use... possibly interference?

So far, I have found the Xvive cordless guitar lead easy to use and perfect for my requirements.In a busy household a conventional guitar lead was often tripped over. Also, whilst playing sitting down a conventional jackplug would often get caught on the chair.I have only used this on small practice amps but have found the signal to be stable, and it has not cracked up, whilst I was considerable distances from the amp.I am very pleased with my purchase.
