I know jade uses a triple rectifier. I get really good AFI sounds outta mine. But more tones from Sing the Sorrow and Decemeber Underground. Try something like this for songs like girls not grey:
Channel 2/3 vintage:
Master- Whatever
Bass- 2oclock - max
Mid- 8oclock-9oclock
Treble-Almost maxed
Prescene-Almost maxed or maxed
Gain - 2oclock-4oclock
This is for triple rec, and I cant remember the exact dial positions, because I just moved to Miami and my triple rec is home in seattle until i moved the rest of my stuff.
Just use a LOT of treble + presence, a pretty good amount of gain, a decent ammount of bass, and slightly scooped mids.
Also, if you have a Les Paul, that helps. I use burstbucker pros, 498T alnico bridge, or a duncan jb to yield the best results.
