Bridge the Gap Between Superior Tone and Stability Bring a new world of heavenly harmonics and thrilling tone to your guitar with the Graph Tech ResoMax NW2 Adjustable Wraparound Bridge. Through its AutoLock feature, this bridge secures tailpieces to the guitar through magnetics — that means no tools required. It even holds together without the tension of strings. Speaking of strings, the ResoMax NW2 comes preloaded with String Saver saddles imbued with PTFE (polytetrafluoroethylene). These saddles make for reduced string breakage and increased stability while tuning. The NW2 fits PRS- and Gibson-style guitars and also makes an excellent compatriot for palm muting. Take it from the guitarists at Sweetwater: the ResoMax NW2 is the crossroads of superior tone and tuning stability.Graph Tech PS-8593-NM ResoMax NW2 Adjustable Wraparound Bridge Features: Bring your guitar to harmonics bursting with richness and tone AutoLock feature secures bridge and tailpieces to the guitar magnetically No
