Until last year, I always had two arrangers, but the second arranger was identical to the first and was a backup - Can't have enough backups when you're playing music every day for a living. However, in all those years of performing nearly every day of the year, I never had a Yamaha arranger keyboard completely fail on me. And, if you folks recall our departed friend Hank Bowman, he had a PSR-2000 that had a drinking problem. Apparently, the keyboard enjoyed the taste of vodka tonics because two of them were dumped into the keyboard with no ill effects.
I guess booze isn't as bad for me as the doctors said.
