"The Boss PW-10 V-Wah offers a classic effect in a virtual package that's packed to the gills with features guitarists love. Built on the foundation of COSM virtual modeling technology, the PW-10 offers six unique wah settings like Double Resonance, Uni-V, and a Voice setting which sounds like a wah fed through a talk box. Want to set your own tone? Tap into the onboard three preset memory bank for dialing in a tone and have it saved to summon on the fly." 

This pedal is used in good shape. It functions perfectly and is missing it's battery door. The univibe setting on this is fantastic. Check it out today.
