Joyo JW-01 Digital Wireless Transmitter and Receiver

1/ How long have you been using it?
A few months. I waited until I had tried it several concerts before posting a review...

2/ Did you try any other models before buying it?
No. Portable UHF VHF are very expensive. I only started to follow what came out after hearing about new technologies with the LINE6 PhRelay (expensive as well). Moreover, it isn't easy to find the Joyo JW-01... I made up my mind because its price is reasonable, and I told myself that if it didn't really suit my needs I could always resell it without losing too much money.

3/ What's the sound quality like?
Its sound isn't flawless. It doesn't have much noise, but it does have some crackles that, evidently, can be heard proportionally to the amp's gain.
I tested it with two very different setups:

3A/ With a VOX tonelab, all digital that is, even if a preamp tube gives the impression of it being analog , it's unusable even with a clean sound. But to be totally honest, the Tonelab's clean sound is full of effects. I think that having two very average digital stages, one after the other, is unforgiving. The signal-to-noise ratio explodes and the dynamics are very affected! So forget it for this setup. I think you could get the same results with a POD.

3B/ With an ENGL savage head and a rocktron repliflex in loop (in series):
(Do note that this head doesn't have a noise gate, but the repliflex features a well-made HUSH.)
The problem is gone. The clean sound is well reproduced and the dynamics fairly respected. To be really convinced I did several comparisons JACK/JW-01 (at home so I had to do it at very low volume levels).
For live, it's more than enough, unless you expect a pro level, but in that case I don't think your are reading the right review here...
True, you must avoid leaving a lead channel with too much gain on when you are not playing, but I think that's acceptable, even without HF.
No problems four times live and half a dozen rehearsals under "real" live conditions

4/ Battery life
It takes one hour to charge via USB. Important: only one 220V charger is included (it must also be said that the chargers are standard) but you need to charge the transmitter and receiver.
Duration, approximately 2h30. Beyond that it still works, but the noise starts to rise... so we need to go back to the jack (or buy two transmitters!) I'd say it's more than enough in 95% of cases.
I can't however be more precise regarding battery life in the long term. In theory it's one of those "memoryless" batteries, that said... it's up to you to trust it or not.

5/ How would you rate its value for money?
Very good, because there aren't any cheaper ones, and it works fine.

6/ Based on your experience, would you buy this product again?
Yes, because it's enough for me.
But if I only had a VOX tonlelab, I would've probably rated it 1/10 stating that it's useless.

7/ Other comments:
- Non "standard" connections, it connects directly to the guitar's jack. I suspect that it won't fit a guitar with a strat-like connector (where the jack is a bit recessed). Although you can certainly use a 1.5ft extension and attach it to your belt. Personally, I think it makes the product more fragile and when it comes to aesthetics, it isn't very appealing.
- There's a mini-jack on the transmitter to connect a mic. I didn't test it.
- Browsing on the Internet, you can find it much cheaper that on a brick and mortar store.
- (I repeat myself, but it's crucial). You need good gear behind it to be able to use it: a good HUSH (or an ISP decimator, I also tested it and it works), and preferably a NON DIGITAL amplification chain.</div>

It's a "plug and play" transmitter for guitar and bass that uses bluetoooth technology. The internal batteries are charged via usb. The transmitter connects to the guitar's jack and the receiver to the amp. No need to attach a box to the strap nor to pull an antenna. It's light and compact.

I've used it for one and a half months and it's my first "wireless".

It's true that the sound changes with respect to a cable: a slight loss of dynamics and mid frequencies. But it can be corrected on the amp. In case you use pedals, you can place the receiver behind them but it generates some artifacts and distortion, so it's better to connect the pedals to an effects loop and the receiver to the amp's input (if you have a recent amp).

The battery lasts more than two hours: afterwards we have artifacts and the sound is attenuated.

I haven't used it on stage yet, only during rehearsals and at home (it's a real treat to play in the kitchen while the amp is in the basement!).

I don't know how it behaves with other transmitters in the same room, especially if they use the same technology.. We will see.

Very good price/quality ratio, competing manufacturers ought to start worrying.
$100, shipped from Hong-Kong.&nbsp;</div>

I have used it two times.
More than 10 years ago I tested some useless low-end analog models
Wired and wireless sound reproduction are not the same
Good value for money.

I read reviews on the site stated above before buying this product.
Given that stand-by time is questionable, I also bought on ebay an external 5500mA USB battery the size of an iPhone for less than $25, and therefore have no problems with battery life.
Receiver/transmitter recognition is very simple.
I started the test with a distortion sound (gear used: fender deluxe strat plus, Pod xt live (both connected wireless, pod connected to a marshall valvestate wired between the line 6's line out and the amp's guitar input).
I immediately noticed that there seems to be some sort of noise gate, as if missing part of the first note, the distortion proves to be a bit less warm or maybe it's just the signal that is weaker.
I then tried with a crunch sound, which lacked attack.

In spite of all of this, it's not bad, but the sound is different when using cables and basic settings.

I added some saturation, presence and volume to all my presets to get the same sound I get with cables.

As a consequence, I saved my presets for "wired" mode, just in case, and also other banks for wireless use.</div>

I looked for this product for a long time on the Internet until I found it here http://www.yoosmart.com/jw-01-wireless-digital-transmitter-and-receiver.html for 69 dollars. Express order placed on June 25, payed via PAYPAL, I received it on June 29 via DHL from Honk Kong. Very well wrapped and without surcharges. For a total of 88.85 dollars (73.03 euros).
I play guitar in a variety band and also in a piano bar. I tested it and started this review after several days. For the time being, it's perfect.
Let me just add that it fits perfectly a Fender stratocaster, I own one.</div>
