Ernie Ball’s Power Peg pro is the newest edition to the motorised pegwinder family, and will allow you to restring your instrument up to 80% faster when compared to a manual pegwinder. It features a wider head, newly engineered, that fits all electric, bass and acoustic guitar tuning machines. The Power Peg Pro is equipped with more torque working with all tension requirements from mandolins and vintage basses to ukuleles. Plus, with rechargeable lithium-ion battery and power adaptor included, buying batteries for your pegwinder is now a thing of the past.
