I'm getting ready to profile all my MTS preamps and have several ways to do it:
Direct line from preamp (no amp or cab)
Red Box 5 cab simulator DI
Rocktron Phantom Cab Simulator
In Randall MTS head to various speaker cabs
Is there one method that is best from these?
I'm going to use these in the studio (not through a guitar speaker) if that makes a difference.
