So i got a boss enhancer, used off reverb. Quite impressive pedal. Does anyone have one of these? Is it more of a phaser that enhances the tone?

A small issue i notice is a strange feedback pitch sound, after i play a chord and stop the strings, i get a echo'y sound from the pedal (yes pedal, check the mogami cables) is this normal?

Not sure why you'd think it's got anything to do with a phaser. 

It's an expander, so it might have a gate which is causing the jitter when you go from loud to no sound.
