RECOMMENDED — not currently owned
The Mega Amp SL20R is a small solid-state practice amp with an 8-inch speaker, so pushing the onboard drive to 7 simulates the heavy Mark IIC+ preamp saturation while keeping mids scooped at 2 to replicate the famous Mesa 5-band 'V-curve'. On your SSS-style Storm ST250, the bridge single-coil lacks the thickness and output of Hetfield's humbuckers, so keep the amp's bass at 6 and avoid over-boosting treble to prevent harshness. For the clean middle interlude: switch the amp drive channel off to clean and set guitar pickup to neck+middle.
