Dude all you wrote is exactly what I experienced in the last 14 days (since I got my JTV-89F). The magnetic PUs sound awesome. The acoustic guitar models combined with the right amp and cab as well. But the rest sounds really, really bad. What in gods name is the Spank supposed to be? Couldn't be further away from the real Stratocaster, seriously. The latency that comes with the models is bareable. The mean feedback I get sometimes from my 2nd guitarists (only when I play the piezos) is not bareable at all. And I had the noisegat cranked up so...why? Bad shielding? The crazy weird "Pling" I get sounds really aweful as well. I tried to get rid off those things with EQing and detailled tweaking in the Workbench etc. but I'm gonna send her back in a couple of days unfortunately. I was really looking forward to this guitar, but I too was blinded once again by the marketing and advertising.......
when it comes down to the modelling (except the acoustic models) the guitar is a joke in my honest opinion. The rest of this guitar I like very much. The Look (except the headstock JamesTylerJamesTylerJamesTylerJamesTylerJamesTylerJamesTylerJamesTylerJamesTylerJamesTylerJamesTyler, seriously Line 6??), the comfort in playing, the magnetic PUs, the tremolo system, and so on, all of this is good.
but that is not why I bought it.... I bought it for the models...and those sound like garbage, sorry.
