Try the grinder boost engaged in the amp block. I find it very effective to tighten amp the bass and add that extra gain and sizzle.Ok guys: time to come out clean.
I can't make it sound like I hear in every MK2 C+ or JP video.
I don't have the same guitar nor pickups nor woods.
I have the Axe FX 3 into a matrix power amp GT1000FX and a Mesa Boogie 2x12 Recto (the vertical one).
The thing is I can't find enough gain even if pushed to the limit. I feel the need to put an overdrive in front of it... That's based on the preset pictures here in this post. Are there any tricks to get that little more gain to go on full LIQUID Petrucci lead mode and tight rhytm aggression?
