Fundamental Series Phaser

The Fundamental Phaser is a versatile digital emulation of a classic phaser with the tonal integrity to live on a professional's pedalboard but with simplified controls friendly enough for even the newest effect pedal users. With 3 types of Phaser algorithms to select from, you can get sounds ranging from light tonal modulation to a highly modulated and resonant phaser.
