NAUJAS!
A true rock classic every guitar player should have.

If you play the real thing—the Dunlop Original Cry Baby wah pedal—you get the real sound. The heavy die-cast steel construction of this classic effect can take all the stompin' you've got in you. Totally smooth, silent, consistent, and easy to control. Made in the USA. Uses optional ECB-003 power supply.
