Yep, sorry, Gary. If NO-ONE made 76 arrangers, I wouldn't be playing arrangers at all! I might have a cheap 61 sitting at home, to help make quick SMF's, but I wouldn't gig it in a million years!
I already bruise my pinky bad enough sitting in on the occasional 61
You could, in fact, ask yourself the almost exact same question... If Yamaha ceased making 61's, and ONLY made 49's, would you move to a company that still made 61's?
