The sound quality is good on both my acoustic nylon string and solidbody. My sound technician says there´s a slight increase in mids on the acoustic but that´s easy to solve. Otherwise the sound is pretty much the same as before. The downside is that there´s a hiss whenever a note is played and disappears when you´re not playing. Very much like a noise surpresor and it´s a little annoying. This is only audible when playing alone and in a band situation you won´t notice it.

Seems fragile but if you treat it with care it will last.

It´s great not to be attached to a cable. And for that reason it´s worth it. The format is very atractive too so for the moment I´m going to keep it. In the near future I´ll buy another one to have both guitars wireless. Perhaps the superior model reciever is quieter so I´ll check it out.
