4-string · Bolt-on (bolts + stainless-steel threaded inserts; carbon-fiber neck rods, double-action truss rod) · headless
headless. Ruinous Guitars' B4-N (Blade Series, 'Narrow' spacing) - a 4-string built to reject mass production in favor of game-changing features and head-turning style. Patented fragmented-body ergonomics with a belly curve, a bolt-on neck using stainless-steel threaded inserts, carbon-fiber stiffening rods and a double-action truss rod, a Richlite fingerboard with 24 stainless-steel Jescar frets (glued to prevent lift) plus a zero fret and a 1/4" TUSQ nut. It is convertible between a headstock and headless: offered with a Gotoh instant-lever drop-D tuning head or a custom stainless headless tuning system (retrofit conversion kits available). Double lap-cutaway (not single-cut), active electronics with an easy-eject 9V battery, and a Pelican tactical case included. Handmade in Illinois, USA. Price on request.
