The Yamaha GA15II is a clean solid-state platform similar in response to the Roland JC-120, so keep gain low on the Clean channel to preserve maximum headroom. Scooping the mid knob to 4 replicates the iconic 80s Metallica studio clean curve, while boosting treble delivers the bright EMG 60 snap. Heavy riff section: step on the Behringer HD300 with Distortion at 8 and Tone at 6.
