mind if I just join you in that wanted ad??? I've tried to find either an SBV-500 or a 550, and from how the internet's come up completely fruitless... I can safely say that it's one hell of a rare bass to get hold of! I even searched globally for one for sale... the only one I found was in japan and would have set me back 1000 for the guitar and 650 to ship it... no way I could afford $1650 in my lifetime with my current rig setting me back $1200... damn I wish I waited!!
