I'm pretty sure Andy was using a Lonestar Classic at the time, which is in the Axe-FX - it's the TX Star Lead. He was also running in to a Boogie V30 cabinet. There's a video somewhere with his settings in it. Let me see if I can find it.
Didn't know it's a V30 cab. Assumed it was the regular C90-loaded cab.
Ye, he mostly uses regular boogie Recto 2x12's with V30s. Resolution was recorded with a 68' Plexi and a 79' JMP (the Stiletto amp wasn't finished when he did this album), and live he uses the Stiletto for those tones
Are you looking for the live sound or the studio sound?
