Hello, sounds like you have the 500 (just like me). You need Java Runtime Engine (at least v.6) installed and the Workbench USB interface. Then you might install Workbench and have years of fun with the model editing. I put Ghost piezos and a high-end Warmoth neck on my guitar. The Ghost piezos allow grounding which rids you of the
character of the L.R. Baggs piezos. A new neck and locking tuners was of course a huge improvment. Bought this guitar new in 2003 and it has been running without since. Try to find some user models out there, there are tons of them.
