No disrespect to ya mate, but I have an Axe 2 as well as the MFC, compared to my HD500, we are talking night and day, nothing wrong with buying on a budget, and the HD is a superb piece of gear. But saying it's overpriced is the same as me asking you what guitars you have. A Fender or a copy? a Gibson or a copy? It is for pro musicians, ........., it is very pricey, firmware updates are regular and sounds are always improving.
Non taken pal. The bottom line: HD is more than good enough for any professional otherwise Steve Howe and many more professional working musicians wouldn't be using it. You clearly said what I said exactly: the AXE II is pricey but keeps improving. I've been hearing this since AXE I that it keeps improving, yet it's always so good almost identical to plugging into an amp. It's not and never will be, nor is the Kemper or any modeling device.
What's being modeled is the sound of a MICED amp. AMP will always sound different regardless whether it's better or worse. If you want the sound of a tube amp, you get a tube amp,. you want the sound of a miced tube amp you get a modeler. If you have HD500 plus DT50 you have the best of both worlds and the difference between that and and AXI II or a kemper is truly night and day difference. If you get HD with DT amp, You get real tube Amp for LIVE use with guitar speakers and also the option of so many different amp sounds and effects, and better yet money to spear. Kemper or AXII two don't give you that, if you want to use them with real tube amps,you're on you're on, it might work and it might not, POD and DT amp is an unbeatable combo because they're customized to work with each other.
