My Jazzmaster Mods For Metal | Squier J Mascis

Can a Jazzmaster handle metal? In this video, I walk through the metal-focused mods I made to my Squier J Mascis Jazzmaster—featuring a Seymour Duncan Nazgûl Rail humbucker, CTS pots, and a fretboard stain for extra vibe.

This offset guitar is usually seen in indie and shoegaze circles, but these upgrades turn it into a legit chug machine for metalcore riffs.
