Quoted from Michael Wagener himself:
"Yes, all the guitars are played through the Randall RM4 and the RT2/50, with both sets of tubes on, mic'ed through the Randall cab with R121s, Ty mostly uses the TopBoost module (Vox) and for the cleaner stuff the Plexi. If he needs clean sound he turns down the giuitar instead of turning down the input to the preamp, sounds fuller."
Thats for the last album.
