HOW do want your rig to be set up? how many cabinets?
are you going to use both amps with its own cabinets?
what about effects for the dual rect?
do you want your rig to be simple to tote around? how many clean, distortion, solo settings you are needing, or wanting.
IS the GCX going to control any DUAL rect amp switching? ,
i myself have used the POD pro xt (with METAL SHOP PACK) with a 2:100 mesa stereo power amp.
sounded great! it was conviently in a four space rack.. great for gigging and very loud!. cleans were immaculate, the crunch was a great cross between a Dual RECT and a marshall's EL34 crunch. harmonics were great. SOlOing was great and stands out.
how are you going to do the signal chain? were you going to use the dual rect only as a preamp? and let the gcx switch both preamps? I also owned a GCX switcher to switch everything. but i got away from rack switcher. ONLY because with a rack switcher, You are alway adding more stuff to your rig. The more you add, the more noise and hums. that is why i went to just a power amp and line 6 pod pro xt.
the pod xt isnt to far from the POD PRO XT. I know that once i got the METAL SHOP PACK, i was able to get a better tone and crunch..
my sound is along TESTAMENT, DREAM THEATER< LAMB OF GOD>
Also we tune to drop A. I also noticed that since we are so LOW, The low end still is tight and GAIN is cuts through.. It has something to do in the combination with the COMPRESSION of the POD PRO XT and the AWESOME MESA 2:100 tube sound! Its real nice!
I may look into the POD 3. i am curious about having the MESA/MARSHALL heavy gain wall of sound.
