Phantasm

Analog Phaser

The ToadWorks Phantasm is the world's first 9V battery operated, opto-analog dynamic phaser with a Center-Axis control pedal (whew!)

Phantasm utilizes vactrols (opto-isolators) both in the signal and control path, resulting in remarkably smooth, ridiculously quiet operation, and the fact that it runs on 9V batteries makes it all the more miraculous. Phantasm sets the standard for noise floor in analog phaser pedals, proving that analog phasers don't have to be noisy.

Phantasm is 100% pure Analog phaser. Go from a light cream smoothie to hopped-up, caffeine laden grind with a swift turn of the Feedback knob for that swooshy 70's sound. Go slow, go fast. Make the sweep window wide, make it narrow. Go shallow, go deep. Control the sweep and depth dynamically. Re-center the whole sweep window, if you feel like it. Phantasm does all this and more, and no other analog phaser pedal on the planet can make the same claim. Period.
