Haven't had the chance to try them out, will thanks in advance. To add another voice, I'd kill for John's no-flubb rhythm ka-chunk tone. I bought one of Choptones' IIC+ packs and love them, but I just cannot dial out some of the low end to prevent flubbing. I'm actually at the point that I'm thinking about picking up a Mk V 25 just for that!
I just profiled my Mk V 25 and my Friedman Butterslax, and got a great chunk chunk/Djent tone from the 'Slax. I'll be posting them here soon.
