A near immaculate example of the Jim Dunlop Bass Cry Baby Pedal.
The first wah pedal designed by bass players for bass players. The 105Q incorporates a proprietary potentiometer* and custom EQ circuitry, specifically optimized for bass frequencies. The Cry Baby Bass Wah applies the wah effect to the mids and highs only, leaving a strong fundamental to hold down the bottom—so you can take solos or throw in fills without ever disturbing your low end. This amazing pedal is used by Flea, Justin Meldal-Johnsen, Doug Wimbish, Robert Trujillo and more.
