Why these settings

Your RG350DXZ has hotter humbuckers vs Speer's vintage-output single coils, so gain drops to 2 and treble to 3 to prevent harshness. The tone knob at 0 is critical — this is THE defining element of Speer's sound. Treble cut hard on the amp compensates for the humbucker's brighter attack vs a Strat neck single coil.

PRO TIPPlay with your picking hand positioned over the neck pickup or even over the fretboard — Speer picks very close to the neck to emphasize the warm, woody fundamental. Combined with tone at 0, this removes nearly all pick attack and creates that signature 'underwater' quality.
