01Overdrive pedal (TS-style or Blues Driver)
RECOMMENDED — not currently owned. The HB-20MFX lacks the power tube saturation of a cranked Plexi. A basic overdrive pedal (Joyo Vintage OD, Boss SD-1, or Harley Benton's own TS clone ~$25) would add the harmonic compression and grit this tone needs. Without it, push amp gain to 8 and accept a thinner, more solid-state character.
The HB-20MFX is a solid-state practice amp with digital modeling—it cannot replicate true power tube saturation. Gain pushed to 7 compensates, but the Bon Scott era tone has more raw midrange grit than the scooped Back in Black sound, so mids stay at 5 (not scooped). Treble/presence pulled back 1 point from the original Plexi settings because the Donner's HSS bridge humbucker is brighter and hotter than vintage PAFs. Tone knob at 8 rolls off the harshest fizz.
