Great points, hurghanico. Funny you said that, and though I just retrieved your last message now, and had more or less decided today that if I was going to get a JTV Variax, I would just get another guitar. Its funny you mentioned the compression factor because that was my exact thought when I watched several YouTube videos demonstrating the JTV, there was a noticeable amount of compression on the electric models. My Variax 700 has some kind of a loose connection around the jack that cuts off the sound so it's got to be fixed. I've gotten a suggestion here to clean the contacts, and another one to buy a replacement jack, but I'm not sure that part would work on the older unit.
Calabasas isn't too major a distance for me to just take the guitar down there and have them fix it. The guitar works perfectly with the XPS A/B box for now, didn't think of using a TRS cable in battery mode (I usually plug into the front of a Fractal Audio Axe-Fx). I even got the old Variax Workbench program to work on my Windows 10 machine :D
