Controls: 3-way mode switch (White Room - bassy and ballsy, Voo Doo - mid-range, Shaft- ear-splitting white-boy treble), an 18dB preamp volume control, Blue Doo distortion Vol/Gain, and Blue Doo distortion overdrive. Color: Something-Humping's Barium Sample Blue. Sound characteristics: Fat, low-end distortion and long frequency sweep gives you an incredibly wide tonal selection within each mode. This enables you to also use the Snarling Dogs wah as a stand-alone tone pedal. Additionally, the Blues Bawls can be used as a wah pedal and distortion pedal at the same time, or you can use it just as a wah, or just as a Blue Doo distortion pedal.
