I own a JTV -69. I used to carry around multiple guitars. I had my Stratocaster electric and one of my acoustical guitars. I had to have a bunch of pedals. I play country covers and all my original stuff and I also play classic rock covers. Going in and out of the two genres gets sticky with having to change out guitars and jacking with distortion and effects. With my variax though all of that is gone.
I have a line 6 amp and I can program my back ups tunes into the amp.
I just create my songs with band in the box...make a copy without vocals and program them into them into my amp. I program the guitar effects and such as well as vocal effects. If I want to play a rock song I just load up the backing for the song that I have created..it automatically brings up the effects and settings for my guitar and vocals. I set my guitar to the guitar I want (like Les Paul setting for rock) I hit play with either with my finger or step on the pedal and start rocking.
If I play a country tune, I just set my variax to acoustic on the guitar I want and set my amp to the song backing and start jamming down.
I haven't mastered the virtual capo yet but I do use the tuning knob for some songs.....I just set the tuning knob to a tuning like "drop-d" or "open g". Then I can get down to something like "Heard it Through the Grapevine" or Honky Tonk Women"
I run into a lot of musicians who play classic rock covers and some who play country covers....but I never run into anyone who play my original tunes, I loose them at that point.

But Band in the Box gives me a way to have a backing band with my original tunes..
Before I use to had to use a drum machine and record all of the parts of my song separate and record them to make a backing track.
I took me a little while to get use to the acoustic guitars on the variax because the guitar is actually and electric body style and at first it is kinda creepy cranking out acoustic sounds on an electric, but I am used to it.
People can't even really tell in your recordings. I had the variax 700 to start with, but it had no pickups and you can't get harmonics out of them..The JTV version solved all of that though and can be used straight up just as an electric.
