I may wind up getting cold feet on this one. But I have two other phasers along with a phase setting in my Bass POD. This one does not get as much time as the others. It's in superb condition. Ya'll know what this is. Here's the description from MXR: This big brother of the Phase 90 offers an even broader range of sounds. Along with the speed control there is a 4-position rotary switch that selects between four different intensities, defined as preset waveform patterns. Great for guitar, bass, keys, vocals, and more! This runs on AC/DC 9V power. There is a battery in the compartment already. Has some velcro fuzz on the bottom side as well. The only trade need I have is for a Nano Pog or other similarly small Octave effect. Price includes insured shipping CONUS. I like PayPal.
