If youre still looking i have the TB7 and it the best guitar I have ever had. Solid, and it feels way better than any ibby i have ever played. Stock emgs sound nice but im going to do the same thing as you and put impulses in soon! IMO go ESP. Always better.
There’s 3 of them to my knowledge. 1 is Josh’s and two others got setup so that jackson could copy the setups for Josh’s signatures so they come out of the factory the way he likes them.
