OVERALL OPINION

Very convenient for non-electric guitar when you want to avoid the microphone stand, a static position or piezo.
I use it hooked the rosette, taken outdoors, mainly with flamenco and Aphex Acoustic Xcitor on a sound system in an amp or RPTE electro - acoustic.
The sound comes out well, better than I imagined, for use scnique or BPS.
This mic is all the same powerful, respects its source and does not hinder the game
