Get a Grip Eh!
Peel n’ Stick “Grip Tape” – Size: (Approx: 10.5 sq. inches)
Colour: “Clear” (once removed from backing).
For the folks that find they would benefit from a bunch of extra grip, the Harp Wah comes with some some very aggressive grip tape which can be cut to personal preference.
If more is needed, this “additional” tape is what you’re looking for.
