Hello,
Here's my current setup with my X3 Live (rough diagram in the Attachment).
Signal chain A allows me to use the Comp/OD module, modulation, reverb, delay, and the Comp(Boost), without an Amp Model; this I route through the 1/4 output into the front of a Vox AC30, set just a little bit dirty.
Signal chain B goes straight to FOH in full stereo, and can again run the Comp/OD module, FX loop (which feeds my TC Helicon Voicelive so it can hear guitar chords to harmonize with my vocals), Amp + Cab model (A Plexi with 4X12 and SM57 off-axis), modulation, reverb, delay, and the Comp(Boost).
Wah (activated by the toe switch) always works on both chains at once
Vol runs Post in Signal chain B, but essentially Pre for Signal Chain A, because it's before my amp! A bit of a disadvantage but I've worked with this for years now.
I can switch between Chains A and B with the dedicated button available, and switch FX on/off on either. Can also turn off one Chain (long press the dedicated Chain A/B switch) and switch between the two.
Cannot, of course, use a Red Comp AND a Tube OD on any chain - only one effect is usable per module and so on.
But if you look at this, there can technically be 2 Amp + Cab Models (even though I only use one), 8 FX (2 Comps or ODs, 2 Modulations, 2 Reverbs, 2 Delays) PLUS the Comp/Boost PLUS the FX Loop PLUS the Wah all running SIMULTANEOUSLY!
Can the POD HD500X deal with this? From everything I've read on the forums, manuals etc, it looks impossible.
Planning an upgrade mainly because the HD models are supposed to be great (and maybe the built-in looper...), but there's no point in getting the HD500X if it can't deal with this setup. It's worked great for me for nearly 5 years now, and the combination of a great tube amp + digital modeling and the ability to run all spatial effects ONLY on the PA while the amp always runs clean or distorted or any other combination makes my band (a trio) sound really big and full. I'm also using a GR-55 for EPs and Organs and horns and - best of all - instant alternate tunings (which are routed from the GR-55 to the AUX input on my X3L).
Would be great if somebody from Line6 or another brother gear-geek can help me make an informed decision..
Cheers
Bruce
