| Mid | 3 |
| Treble | 7 |
| Master | 6 |
The Glarry GA-20 is a small solid-state practice amp with an 8-inch speaker, so the onboard Drive switch is your primary gain engine today. Keep the bass capped around 6 to prevent the small speaker from flubbing on palm mutes, and scoop mids down to 3 to mimic the early thrash curve. Adding a ProCo Rat down the line will significantly tighten the front-end attack, at which point you would switch the GA-20 to its clean channel with gain dropped to 2.
