Why these settings

The First Act MA155 is a basic solid-state practice amp with only bass and treble controls, so the NUX MG-300 handles all amp emulation, crunch gain, and modulation. Keep the physical amp set completely clean with gain low to avoid harsh double-gain distortion over the modeler. Selecting the Jazzmaster's middle position mimics the hollow, chimey midrange of Jimmy Page's dual lipstick-pickup Danelectro in DADGAD tuning.

PRO TIPTune the Jazzmaster to DADGAD (D-A-D-G-A-D) and strike all six strings with a heavy downstroke to let the open ringing drones create the massive orchestral wash heard on the record.
