For Pasta4inch and Matt-77 here's some more info and pics for my Rainsong Graphite Acoustic Electric bass. A full body shot, a head shot (with a nice body on it) and a shot of John playing it in the late 1990's outside the House of Blues in LA. I bought it from Jimmy Haslip a couple of years ago and he got it from John Entwistle shortly before John passed away.
Some background - acording to Rainsong, they made less than 10 graphite acoustic electric basses before stopping production on them and focusing on graphite acoustic electric guitars. This was the only custom bass they ever made and it was made to John's specs. The bass still has the original strings John put on along with a spare set in the case. It plays fantastic, lots of punch, depth and volume for an acoustic bass as only gets better amplified. It's in mint condition and with the all graphite carbon fiber weave visible thru the high gloss coating it's breath taking. The master Luthier that built the bass also did a beautiful Hula Girl inlay on the headstock and a double shark inlay at the 12th fret. Here's some more pics, enjoy:
