Why these settings

The Gear4Music GA-15 is a budget solid-state practice amp with limited headroom and a brighter, thinner voicing than a Marshall JCM800. I've pushed mids to 7 (vs original's 5-6) to compensate for the amp's natural scoop and kept bass at 5 to avoid flubby low-end that small speakers can't handle. Gain at 7 will get you into crunch territory, but the amp won't deliver true tube saturation—expect a tighter, more compressed distortion. Roll treble back to 6 to avoid the solid-state ice-pick highs.

PRO TIPYour LA-series guitar likely has ceramic humbuckers that run hot—dig in with your pick close to the bridge for that tight, percussive palm-muted attack Sum 41 relies on, and keep your fretting hand muting clean to prevent mud on the power chords.
