As much as I enjoy getting new stuff, I think this PA4X is going to be IT for a long time. It would take something pretty revolutionary for me to change again.
All my old arrangers have been sold and shipped. What an ordeal last year was, trying to get it right. I'm convinced I am a top-of-the-line-arranger-guy. I need the controls, features and extras of the high-end gear, even though middle of line options such as PA900, SD7, BK9 and PSR S-970 have an awful lot to offer for the dollars. (I had ALL those in the past year, plus PA3X).
Now I have a TOTL that does everything I need, and has a small enough footprint and weight for me to handle easily.
As Minnie Pearl used to say, "I'm just so PROUD to be here!!"
