Why these settings

Because the ProCo RAT2 acts as the main gain source into the Marshall MG50DFX's Clean channel, amp gain is dropped to 2 to prevent muddy solid-state clipping. The RAT2 Filter is dialed low (counter-clockwise) to emulate the bright, cutting peak of a Dallas Rangemaster treble booster hitting an AC30. Les Paul humbuckers have a thicker low-mid profile than May's Burns Tri-Sonics, so amp bass is pulled back to 4 and mids are pushed to 7 for vocal articulation.

PRO TIPUse a metal coin (like an old sixpence or a hard brass pick) and pick aggressively right next to the bridge to replicate Brian May's signature metallic attack and rich harmonic squeal.
