The first wah pedal designed by bass players for bass players. the 105Q incorporates a new proprietary potentiometer and custom EQ circuitry. specifically optimized for bass frequencies. The Crybaby 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 of the Red Hot Chili Peppers. Justin Medal-Johnsen of I Am a Robot. Doug Wimbish. Robert Trujillo of Metallica. and more.
