D'Addario PB047 Phosphor Bronze Wound Acoustic Guitar Single String, 047

Patented features like the free-floating rotor-drive system, rotating swivel spring and infinitely adjustable cam, are aligned to create a more direct transfer of energy that optimizes the stroke for more power and precision. The patented 9000 series free-floating rotor drive system allows the shaft to turn independently of the rotor directing energy from the pedal board straight to the beater. The design also uses friction-reducing ball bearings to optimize the already incredibly smooth, gravity-defying action. The patented floating swivel spring increases efficiency on the down stroke and return stroke, creating less resistance and an incredibly smooth feel. The 9002 PC features also include an infinite-adjustable cam, allowing the pedal to be easily set from accelerator to turbo drive or anywhere in-between. The 9002 PC includes a nylon strap and can be easily converted from chain-drive to nylon strap.
