There isn't a ton that I haven't tried that would be interesting to me
Some of Larry's less common stuff like Rock Wizard, Wrecky, and Purist - Great dude, trust his ear, don't doubt they all have something special
GZ hellion 1000% - Jeremy is a great dude and I trust his ear, the MOAB+ i owned was incredibly good
Eddy Lenz hot chili - Love his playing and demos
Lickliter Scalpel - interesting and different type of tone, doesn't sound like it's copying anything blatantly
A legit Cameron CCV, played an atomica and it was incredible for lead stuff. Basically how a friedman SHOULD sound IMO
Wizard Hellrazor maybe, clips sound good, and like wizards, but unlike many here I think the metal and MC2 sound better on recording than in the room.
KSR Orion - they have a really cool take on the more modern sound, and I'd like to try one
