I am actually playing my dream rig. Pretty much - maybe a wireless system would be the only thing I don't yet have.
Guitar:
Amps:
Mesa Boogie Triaxis
Mesa Boogie 2:90 Power Amp
4x12 Mesa Cab
Effects:
TC Electronics G-Major
Pedals:
BB Preamp (for leads)
Other Gear:
Rocktron Patchmate
Rocktron MidiMate
Fuhrman Power Conditioner
Decimator noise reduction rack unit
Ernie Ball Stereo Volume Pedal
Mark Tremonti Wah
Boss Tuner
PCM600 In-Ear monitor system w/custom molded ear buds
About the only stuff I'd add would be the rack mounted Crybaby Wah (I hear it's absolutely awesome) and a wireless system for my guitar. I'm sure I could add a few more pedal effects (I have 7 more spots in the PatchMate available).
But for what I want I love my rig. I have serious versatility with the Triaxis - I have 100 presets I can configure. I have 8 separate tone paths through the Triaxis - I can get any tone I want.
