Nothing special with the settings. I used the 5150 and Rectifier Orange sims on the VG-88, almost all settings around 50 (12 o clock), used a Tube Screamer in front. Then in Revalver I used the Kitty poweramp, doesn't add a lot but it sounded better nonetheless, for a cab sim I used 2 of Keiffer's impulses pack (18b-v4-4x12-v30_57nx-421.wav and 57 +3_00.wav, my 2 favorites).
I think this is one of the best modeled metal tones I got uptil now, and I didn't even use any EQ or compression or whatever on the guitar sound yet. It was done quite fast. Does anyone here own the GT-8? I wonder if the modeling sounds better then the GT-6.
