wow, I used to have one just like it but a 1966 EB-2, it sounded like "To Sir With Love". And it was hard to play. Sold it to one of ABBA's bass players in Norway
curiously, Gibson has gone thru at least 2 cutaway designs in the 335 body, the original cutaways were fatter, then the second design became thinner, and now, it looks more like a Yamaha cutaway.
