HOLY CR@P!!?! Firmware v5.01 is... ....stunning! Amp builders should probably start learning to write code now. UPS arrived early enough for me to have time to install the AxeII in a portable rack case, set it up and check to see that it was functioning properly. Beyond this I really didn't spend any time with v4. Firmware update via USB was quick and painless. It took a little longer to send the v5 preset banks so I paged through the manual a bit while waiting. I power cycled the unit when complete and started with preset 000... ...Wow! WOW!! Dynamic response is nothing short of incredible! Other observations followed almost immediately: the 'feel' under my fingers is right, it sounds and feels like I'm a direct part of the signal chain, the amps sound...amazing! I don't really have much more to say as I sort lost track of time for a while just scanning through the presets. Couple more quick observations though. The clean tones are amazing - warm, rich, and dynamic. High gain tones are BIG FUN!! Finally - the JTM45 model is fantastic! (as is the Plexi Treble, USA models, Wrecker, Buttery, the Fenders all sound amazing... I'll stop here). Cliff - bravo sir! Extraordinary achievement! Thank you! Man - this is going to be fun!!
