Why these settings

The Rockville G-Amp 20 is a compact solid-state practice amp with standard 3-band EQ, so we push the onboard drive channel gain to 8 while severely scooping the Mid knob down to 2 to mimic Dimebag's iconic parametric EQ cut. The Treble is dialed high to 9 to replicate the biting top-end sizzle of the Bill Lawrence L500XL pickup, while Bass sits at 8 for low-end punch without flubbing the 8-inch speaker. Clean intro tone: disengage the amp's drive switch, set volume to 5, and switch your Ibanez pickup selector to neck+middle.

PRO TIPDimebag's attack is defined by aggressive pick angle and hard downstrokes right next to the bridge saddles; pick firmly with a heavy, sharp pick to get the signature metallic bite and razor-sharp squeals on the GIO's bridge humbucker.
