Saturday night, I played a high energy cocktail hour before a big dance party, and they pointed to an area that had a very nice Yamaha grand piano. If it was a quiet thing, I might have been tempted to use the acoustic, but there were 2 problems I had with that ...
1) the piano was on a dolly, so it sat too high for my comfort (if I used the bench)
2) My vocal processor is built in the kb, and all my cables are pre-measured to fit neat, and tidy on the stand I carry, so ... I set up my (X) stand sitting just over the piano keys, and stood behind it. My Bose was to the side, and it filled a long room of 40-50 noisy guests just wonderfully.
