It’s not my first rodeo, and usually I get compliments on my tone and questions about how I get it. But yes I have considered your suggestion thoroughly. As my post says I also own the POD HD 500 and I can PROVE that the two units are ridiculously different. If anyone has the same two units just compare a simple patch like Duffy’s Cult, pretty much a straight up JCM 800. On the original POD HD, if you turn ALL the cabinet tuning to zero it’s sounds fantastic, even at high volumes. The 500HDx doesn’t even sound like the same product let alone the same modeling. So yes I have had both units on at the same time in the same environment using the exact same settings and models and they are not in any way the same. Furthermore because the cabinet modeling is useless in the HD500X the upgrade to the extra models is just as useless, (they got me for that 100.00 bucks as well). And finally if you do your research (here on line 6 forums, WTF? line 6) you can see it is a common problem and using a 3rd party cabinet simulator is the solution.
