I've had a Fretless Gibson The Ripper for a while and loved it, did some gigs with it but had to sell to get some cash for the Wall of deaf
Btw: this bass can also be seen in the Alembic movie on the Futures channel. (I think it's in the beginning, can't open it right now)
@ Keith: Spalted Maple fretless basses are tha bomb!
I love your Orion, lost some keyboards watching yours :-)
