The ESP MX i have is one of the nicest guitars I've ever owned. It never goes out of tune, is perfectly set up and plays effortlessly. There is a huge difference between the MX and my Gothic Explorer (which I also like). It's not even really close.
I was at both Detroit shows and I agree with you. It was awesome and so glad I went except for my 3am wakeup call to catch an early flight back to DC. @JimAnsell what section where you in? I was in 126 row 4 and saw a father and son right in row 1 I think. Kid was wearing red "ear muffs"...
