Makes changing strings a breeze.
The Planet Waves Auto-Trim Tuning Machines automatically cut off excess string while you tune up your guitar. An individual string clamp holds the string tightly in the tuner, so there's no need for multiple wraps around the tuning post. A precision 18:1 gear ratio provides smooth, exact tuning, while virtually eliminating backlash and slippage.
The rugged, die-cast outer casing houses precision 18:1 bevel and worm gears, a string clamp, and a hardened-steel wire cutter. Restringing has never been easier: simply insert the string, tighten the clamp, and tune up. The Auto-Trim Tuning Machine does the rest.
