This is a great effect. Ultra rare and very functional. It has a speed control and a Peak knob which allows you to select the frequency range that the phaser peaks, so you can emphasize the lows, mods or highs. Very neat device. Runs on a 9Volt or external power, has a bypass input, an expression pedal speed control input and it is the size of an MXR. Very versatile. I really don't want to sell it but I have five phasers and I need to fund some new gear. It is in perfect operational condition but the paint on top and sides is worn a bit. So cosmetically it is not pristine but it is 100% functional. $200 shipped.
Pics to follow after work.
Thanks for the space.
