As you know changing strings can be a hassle so Some years ago I decided to create something that would help change my strings out. Thus became the “The Spin Doctor String Installer”. It is made with ABS Plastic tool you put in any Cordless Screwdriver (Not a Drill) when changing out your strings on a Electric Guitar, Acoustic Guitar, Banjos, Mandolins or Pedal Steel Guitars. It makes the job so much easier and your guitar stays in tune longer. Once you own one there’s never going back to those Pesky hand winder things. Hope you enjoy it for years to come.
