Hey thanks all for the responses. I am not the original owner, to answer one of your comments. I got it from a music store in NY, they had never sold it but it had definitely been played. It's definitely an 89F, to answer another comment above. Triryche, I've read that section of the manual a few times and like you I think the answer is *mostly* there. Let me ask you Variax experts a basic question....Ignoring alt tunings for a moment...If I simply want to select, say, one of the Chime models, and I'm in standard mag pickup mode (no models or alt tunings), I need to (a) quickly depress the guitar selector knob, then (b) rotate the knob to the desired model, and © use the 5 way selector to potentially select from choices within that model. Yes? I think that's correct, and I wish the manual would be as clear as that.
