The Moogerfooger 12-stage phaser is one of the most advanced pedals I have ever used. The detailled knobs and switches allow for a wide varietal distortion in the volatility of oscillating subjugational wavelengths. This is one of the only A/D conventional pedals that I have used other than the antisematical synthomaticational clocking mecktroniter that I have constructed. However, that is a bit larger and more complex. But this pedal can be used for an enormous variety of different applications. I was able to set the phaser to dip beyond the 12th root of 2 above the frequency of the note I was playing. This allowed a sound which sounded like an oscillating chromatic excersize dipping above and below the note I was playing. Thats just one of the simple parts to this device. In shorter terms... This pedal is to me the most enjoyable and easiest to use pedal out there. I strongly recommend it for any musician
