Why these settings

The original Twin Reverb clean tone is glassy and full-bodied. The Katana's Clean amp type approximates this well — I dropped treble to 4 and presence to 3 because the GRG170DX's Infinity humbuckers are brighter and hotter than Hunter's Novax. Rolling your tone knob to 5 is critical to achieve that warm, rounded jazz-clean character without mud.

PRO TIPHunter's signature sound comes from playing closer to the neck pickup with your picking hand positioned over the fretboard (not the bridge) — this softens the attack and emphasizes fundamentals over harmonics, giving you that smooth, vocal-like sustain.
