Although originally designed to keep standard tremolo system equipped electric guitars in-tune, the Guitar NutBuster® also offers noticeable tone and sustain enhancing benefits that are especially apparent on hardtail electrics and acoustic guitars due to its 2.2 oz. solid tool steel mass resting and resonating directly behind the guitar nut.
Most importantly, the added convenience of On-Board Micro-Tuners offers the ability to make fine tuning adjustments which is extremely useful to have on a hardtail electric or acoustic guitar!
