The jazz guitar sounds like the typical Roland SuperNatural jazz guitar when it makes some slight unintentional glissandi (happens if you don't play it solo). So, unless you have a Jupiter or Integra, it is most probably the BK-9.

No idea... Sorry, Fran, but if that's a BK-9, it only goes to show how just about ANYTHING can be made to sound bad by bad playing!

Tip #1... If you are playing a jazz guitar solo, mute the jazz guitar arranger track..!

Tip #2... Write some changes down before you start playing!

Love ya, man, but this is not your best work, LOL
