I'd like to add my thought on this (and the video)
This is a complete non sense, if Tech 21 thing is presented as an FRFR system, micing this setup is absolute bul******t
If pod is studio direct with cab sim (them mic sim) , what's the needs to remic a virtual mic ????????????
Lot of demonstration use the remicking thing , despite this FRFR is just a monitoring for player.
Also in this way i believe now that using FRFR as a live amplification system is weak as this will simulate a loud micked amp, not a live amp, that 's a bit different
