Last nite i had the pleasure of watching 2 hrs of Ottmar liebert. http://www.lunanegra.com/ He is a spanished influenced flamenco guitarist who brings along a fusion band. His bassist Jon gagnon was simply put, rocksolid, and tastey. Jon had a huge presence and voice on a 4 string fretless which sang like an baritone opera singer. Two things: I couldn't place the bass at all it. had a EB-like headstock and a body shape of something like a JP and a morsh. Second- his tone was so full of mwah, but soulful and crying, his fretboard was definately coated with something shiney. Any ideas?
