I was interested to read how recent the V2 firmware was. I bought a GT100 yesterday and it upgraded the firmware straight up, so I have not experienced the GT with the old firmware at all. I presume I got V2 because I have the Dual Showman amp available - and doesn't it sound great too! I bought the GT100 because I wanted those lovely clean Fender amp sounds. The twin sound is just what I wanted (until I heard the showman). The next sound I want to dial in is the hot rod deluxe. The other sound I am chasing is a nice jazz tone. I have two hollow body guitars, a Washburn ES-175 copy, and an Epiphone Sheraton. I downloaded a few tones others have posted and they are close, just some tweaking required for my particular guitars I expect. Enjoying the GT100 !!
