Why these settings

The THR10II's Boutique Clean voicing delivers the headroom and sparkle this tone needs. Your Pacifica's neck humbucker approximates the warm, round quality of a 70s studio clean tone. Treble at 6 and tone knob rolled to 6 prevents ice-pick harshness while maintaining clarity for the volume swell technique.

PRO TIPThe magic of this tone is 100% in the volume knob technique — practice swelling into each note by rolling your pinky on the guitar's volume knob from 0 to 10 as you pick, eliminating the attack entirely. This creates the 'pedal steel' illusion that fooled listeners for decades.
