Sublime simplicity. Purr is a one-knob optical vibrato that provides phenomenally warm, smooth, and sexy pulsations. Its throbbing is hypnotic, immersive, and less fatiguing than most modulation effects. Purr just seems to gush.
Hey — doesn’t a modulation pedal need separate rate and depth controls? Not necessarily. This one-knob scheme just works. Rate and depth are linked in an elegant ratio that simply sounds gorgeous at all settings. Like a rotating Leslie cabinet, Purr sounds coolest out of sync with a song’s tempo.
Purr runs on standard 9-volt power supplies, but its internal charge pump generates 18 volts for nice, airy headroom. Separate wet and dry outputs create bitchin’ faux-stereo through two amps. Coordinated guitarists can spin the oversized knob with a foot.
Purr was created in San Francisco by me and is built in Michigan by skilled craftspeople paid a fair wage. It comes with a lifetime warranty.
TO USE: Advance the knob for faster, deeper throbbing. The LED flashes your current vibrato rate. Coordinated players can spin the knob with a foot. For primitive faux-stereo, connect the wet and dry outputs to separate amps.
… and here’s a song I recorded last year using the final prototype. It’s on at a very subtle setting throughout — almost a subliminal effect. I like using it for this kind of understated animation. - Joe Gore
