I used mine yesterday at an Allstars gig (members from different bands, performing some populair rock and metal songs)
First time onstage with the Fembic in +/- 7 years, sounded awesome! :-)
Rig was an Ampeg SVT 3 pro (amp I used for years before the full Mesa rig) and an Ampeg 1540 cab (4x10 + 1x15)
Used it on Smells like teen spirit (Nirvana) and Paranoid (Black Sabbath)
I only brought it for the Nirvana song, but broke a string on my '83 Spoiler during Ace of spades (Motorhead) The Fembic proved to be a worthy backup :-)
Also did backup/lead vocals only on two ('tallica) songs, first time ever without guitar/bass onstage for me... :-)
I think there will be some vids shortly, will post here if topic is still active.
