I’m sure there are other videos out there doing this same thing, but here’s mine!  I play a Fender Pro Tube Pro Reverb amp.  It’s a newer (2003?) blackface-esque 1×12 that has a tube powered tremolo.  This is not a perfect example of what Catalinbread was going for with the Pareidolia Harmonic Mesmerizer, but it’s close.  I believe I’ve mentioned before (maybe in the product description) that the Catalinbread pedal has a lot more range to it, but I think this video shows just how much.  Not just the speed, but the intensity of the effect.  It does so much more from those two knobs.  Pretty impressive.
