Hi Rikki,
Do you miss it not having electric guitar (overdrive/distortion etc etc) capability?
Also from what I read at korg forums, the guys who made the DVD's are making the guitar mode one available to existing DVD owners ONLY...
So if all you want is a DVD on guitar mode, tough, you gotta buy them all.
Personally, I don't need the other DVD's as I know my way around the PA's pretty well, but the guitar one might be a bit interesting, not that it would take that long to figure it out.
It does seem pretty straightforward after a recent play-around with it I had.
The DVD would be interesting. BUT not if it comes at the cost of the rest of the series too.
