Behringer · pedal
The Behringer B-Tron III is an envelope filter pedal described as a faithful recreation of classic auto-wah effects that defined the 1970s funk sound. Three filter types are selectable: Low-Pass (LP), Band-Pass (BP), and High-Pass (HP). A Sensitivity control adjusts how the filter responds to playing dynamics. Up and Down modes switch between an upward wah sweep and a downward filtering voice. True bypass. 9V battery or DC supply. Part of Behringer studio-grade effects series targeting vintage 1970s funk filter tones at accessible price points.
