Product Description:Catalinbread Pareidolia in the original art style. This pedal is an excellent harmonic tremolo effect that really manages to bring the sound and feel of the tremolo section from a Brownface-plate 1961 Fender Twin Amp to any rig. A harmonic tremolo operates differently from a traditional tremolo circuit, which would simply modulate volume. Harmonic tremolo is really a high and low pass filter operating at the same time to give you the volume modulation effect with a nice added phasing touch. This sound is unique and instantly recognizable, and the Pareidolia really brings the powerful feeling of amp tremolo into a compact pedal format. It can handle up to 18V as well for extra headroom and push.
