There's room enough in my heart for one of each of the top 3. Kemper is awesome because its awesome. HX Stomp is killer for factor + battery powerable. Can't wait to take an FM3 for a ride at some point. Headrush...they're stuff is just too big. I've got room in my heart, but not on my floor. Atomic...meh. Forces me to have to think way too hard to make it work the way I want a rig to work, and missing key amp selections. Boss -- love the form factor of the GT-1000. Indeed, if that's what a Helix LT was like, I'd find it awfully tempting. Just haven't used Boss multi stuff in so long I have little interest in remembering how to work and live in that environment for now.
