I have the standalone UST-only version in my Canteri, and am very chuffed with it, so I got myself this combo with a mic and fitted it in my new guitar.
It was quite an involved installation with the UST being glued to the bridge plate (working through the sound hole), but it worked out ok.
I did a preliminary test in my acoustic amp and it sounds great. The two sources are fed into separate channels of the belt-clipped pre-amp with a stereo cable, and then with a standard 1/4" mono jacked cable out to the amp/desk. That way both channels can still be controlled seperately on the pre-amp.
Next I need to do fine adjustments with the pre-amp in a PA.
I love the natural sound of it, and the mic adds that 3rd dimensional magic that only a mic can provide.
The bonus with this rig is the battery is in the pre-amp outside the guitar.
