Cable works out of the box on PC/MAC. Build quality looks ok, nothing lose/wrong with the product out of the box.
Input starts off very well, but within about 13 mins of playing there's about a .25 second lag. After 20+ mins it's > .5 seconds. Gets disturbing and confusing when playing as it's too out of sync.
Unplugging and replugging the usb end resolves the issue. You can use ASIO4all on PC to resolve the lag issue, but this introduces a lot of background noise depending on the quality of the electronic insulation of your PC/Soundcard.
Have since replaced with an iRig. That's perfect, although considerably more expensive.
Was great to test, is super cheap, but doesn't work for more than a few minutes. might as well just go straight to a working product.
