01Zoom G2X Four — Tube Screamer model (TS808)
Use the TS808 or Tube Screamer model as an always-on clean boost — drive nearly off, level at unity or slightly above. This adds subtle compression and harmonic richness without audible distortion
The Hertz SG15 is an unrecognized small practice amp — settings are based on near-universal knob names and the original tone's frequency character. Mayer's Two-Rock is a clean, touch-sensitive boutique amp; your solid-state amp won't replicate that dynamic response, so keep gain extremely low (2) to stay clean and let the Zoom's TS model add the subtle compression. Mid at 6 preserves the vocal, piano-like quality of the original. Roll volume knob to 8 for headroom to push dynamics with your fingers.
