About Drop B Tuning

Drop B tuning (B-F#-B-E-G#-C#) takes the guitar into territory traditionally reserved for 7-string instruments, delivering a subsonic heaviness that you can feel in your chest. This tuning has become essential in modern extreme metal, deathcore, and djent, where low-end clarity and rhythmic precision are paramount.

Drop B represents the practical limit of what a standard 6-string guitar can handle before tone quality degrades. With the right string gauge (12-60 or heavier) and proper setup, it delivers the crushing lows of a 7-string while keeping the familiar 6-string layout. Bands like Architects, Periphery (on some tracks), and Parkway Drive have used Drop B to create some of the heaviest riffs in modern metal.
