Maxon were in fine form in the early 80s, having already to prominence with the Tubescreamer a few years earlier. This is a glorious vintage phaser, with a great range of sweeping wobbly goodness on offer. The feedback control sends the signal back through the effect again, brightening the signal and adding more wonk. It's a beautiful sounding phaser with a gooey, warm voice.
