This beautifully crafted American made Classic '57 features the Bunker™ Sustainium™ Tension Free Neck System. Our Tension Free Neck allows for greater clarity, better tone, more sustain, and superior crunch sounds. The Tension Free Neck does this by removing the pressure from the neck normally applied by the strings (160-180 LBS average depending on gauge). This is done using Bunker's superior Sustainium™ adjustment technology. Among many other things, this allows the neck tone-wood to freely resonate. The Tension Free Neck™ is set on an alder body with an elegant flame maple top, with two single coil pickups, a humbucker pickup in the bridge position, and locking tuners. This guitar also has a quality graphite nut which helps to achieve great intonation. This Bunker™ Classic 57 is created using advanced manufacturing techniques, the finest components, and the best of Bunker Stump to Stage™ tone woods. All these features are paired with a level of care and innovation that Bunker™ has delivered for generations. Bunker™ believes in it's products and we want you to believe in our products too. Because of this, our Classic 57 has a 10 Day Money Back Guarantee, also included is a our Lifetime Warranty on the Sustainium™ Tension Fee Neck, and we include a 1 Year Warranty on parts and workmanship.
