Agree with John C here, but come on Don the PA1000 can sound way better than that. ( see my mail to you and resources)
For starters you could use a better and louder bass in this version of Summertime. Tip: if the drums do not shine/come out right , boost the volume by adding the insert effect to drums and selecting EQ7 band. Boost all settings to + 5.
And imho keep down the reverb on most stuff, I rarely use reverb on the drums and piano, just a teenie weenie bit.....
