Why these settings

The Fame Forum IV features humbuckers, which produce more mid-range thickness and output than Mayer's Big Dipper single-coils. To compensate, roll the guitar volume back to 8, pull the Kemper profile's Mid control down to 4 for the iconic scoop, and rely on coil-splitting to the neck pickup if available. Keep profile gain at edge-of-breakup so hard thumb-plucks dig into subtle grit while fingers remain pristine clean.

PRO TIPPlay with the meat of your thumb on bass notes and index/middle fingers popping the higher strings without a pick; striking upward with the pads of your fingers is essential to replicating John's round percussive snap.
