In this episode of the Fret Files Podcast, Eric goes over some of the contents of his new book, "Solid Sound." Then comes listener submitted questions, including questions about grounding volume pots, adding a volume control to a Piezo pickup, de-glossing guitar necks, the P-13 pickups and flipping magnets over to get an out-of-phase sound, and a discussion about the different eras of Fender guitars.
