The FDR-1 effects pedal is based on the Fender 1965-era Deluxe Reverb ” a coveted tube amp known for its natural touch response and distinctive, snappy, overdriven sound. In conjunction with Fender, BOSS designed this stompbox to re-create that legendary tone. Features include the same controls found on the original Deluxe Reverb: Level, Gain, Treble, Bass, Vibrato, and Reverb. The FDR-1 pedal also functions perfectly as a pre-gain pedal placed before an already overdriven amp to add the tone character of the Deluxe Reverb.
