Read the excellent description on the product's website.

UTILIZATION

Extremely easy to use, just unplug the speaker cable coming from the amp head and insert the JDX
and then connect the XLR output to the desk.
This product can replace the line outputs from amps and even the outputs with speaker simulation.
The user's manual is clear.

SOUND QUALITY

The sound is good.
Compared to it the standard amp outputs sound extremely nasal. The JDX doesn't reproduce the amp sound recorded with a mic, but I was very pleased as soon as I heard it and it's even better with a good EQ on the desk.
When I decrease the amp volume and increase the gain in the desk it sounds like a very good solid-state amp. When I increase the amp's volume because I'm playing on a small outdoor stage the sound is still nice and powerful.

OVERALL OPINION


The easy setup and the sound quality convinced me and I don't use a mic anymore on small stages.
I know it's a little bit expensive
but I recommend it if you are regularly on tour like me.
