Meet FRED = Filter + Resonance + Envelope + Distortion. FRED is amplifying, twisting and swirling frequencies in sometimes chaotic ways and will sometimes lead your tone into many unpredictable directions. FRED is very sensitive to what you feed it with. It was originally designed for Electric Bass Guitar but turned out to be fun to play with any signal coming into it. Chasing the perfect tone is a never-ending task and when the technical side is satisfied, the aesthetics are in line. This pedal is a creative Envelope Filter and with its wacky sound color it will spice up your guitar tone by adding a certain dose of vocal characteristics. For the grit lovers an overdrive signal path is included and accessed by pressing the MOD button, which in combination with the Envelope Filter generates pronounced distortion, especially in the bass frequency range.
