Feature:
Simple to use volume and tone controls neatly hidden just underneath the sound hole.

Quality:
Super high quality. Well thought out. Sturdy design. I'm sure it will outlast the guitar.

Value:
Worth every penny.

Desirability:
Does not interfere with the look of the guitar because all parts are hidden from view. Brilliant design.

Sound:
Simply put, this thing sounds awesome! I did the install myself into a Fender Telecoustic that I almost gave up on. The guitar went from sounding mediocre to stunning. Easy install and brilliant sounding. Good enough to record direct from the guitar. I couldn't be happier.

Ease of Use:
Not much learning curve. Just dial in your EQ to get the sound that you want. It just sounds great at any setting. I like it bright but if warm or dark is your taste there is plenty of that too.

Support:
Didn't need any support. Downloaded the installation instructions from Fishman site and less than an hour later I was stunned by the sound coming out of my guitar.

Overall:
There is nothing that I don't like about it. I would replace with the same one if anything happened to it.
