The Behringer UF300 Ultra Flanger is a versatile flanger pedal offering classic and modern modulation-based sounds. It emulates vintage analog flanging effects, along with chorus, vibrato, and short delay. The pedal provides two modes: MODE I with negative feedback for flanging, and MODE II with positive feedback, perfect for vibrato-style effects. It features MANUAL, DEPTH, RATE, and RESONANCE controls, and can be powered by a 9V battery or DC power supply. The UF300 offers a wide range of effects similar to the original flanging technique used on reel-to-reel tape recorders, similar to other effects like the Chorus pedal.
