• OVERVIEW •
Use the ‘slack thwack’ to access the bass guitar register in your lead playing (well, all but the very lowest 5 notes of it). Tuning the 6str right down to A – downwards a perfect 5th – will bring a strange buzz…but opens up some unique textures and grooves. Some guitars will handle it better than others – give it a try on yours!
The huge width exceeds that of many 7-string guitars, and the low bass-string separation is somewhat reminiscent of a harp guitar. And to extend the basic idea to other keys: tune the 6str down to your chosen root and see where it leads. Some real jam freedom to be found here.

Antonio Forcione’s virtuoso nylon-string trickery on Acoustic Revenge is hands-down the best showcase of the slack thwack (“I use extra hard tension on the bottom E…it still has to hold”). Also used on Bangers + Mash (Jonny Greenwood), Caligulove (Josh Homme), No One Loves Me and Neither Do I (Them Crooked Vultures), Citizen Erased (Muse), Moor (Every Time I Die), Sorceress (Opeth), Strat Riff (Bluffalo), and Stella by Starlight (Jeffery Matz).
(And for a few highlights from the actual harp guitar – which long predates our past century of recorded sound – try out George N. Dudley, Pasquale Taraffo, Alfred Karnes, Michael Hedges, Muriel Anderson, Andy McKee, Antoine Dufour, and Jamie Dupuis.)
