I've never played or heard one. They were heralded by Epi as the next big thing and then went away quickly and quietly. By nature, these things are hilariously neck-heavy (someone who owned one once said), which can't be rectified but lived with, and the pups aren't great, which can't be lived with, but can be rectified. They hardly ever show up so sales during their comparatively short lifespan (two years or even less) must habe been minimal.
I'be played with the thought of getting one to pimp up ... TB Plus pups should work magic here. Maybe I should go for this one if no one else wants it here?
IIRC, there was also another 5 string Epi model introduced at the time, was it an LP?
