The PBA-2's Funk Wah is akin to the Wah used by Bill Dickens, Rudy Sarzo and Dave Pomeroy. The pedal is great for use with 5, 6 and 7 string basses where the lower string frequency is too low for standard wah pedals. The PBA-2 is also great for 7 string and/or detuned guitars. Additional features include Wah level control, LED indication, easy access battery compartment and a two-year warranty.
