I've had this pedal for about a year now and I'm not impressed. The concept of the Tone Dock pedal is unique but unfortunately suffers from lack of quality. I own the "Verbzilla" and "Echo Park" modules to plug into the dock. Sure, the pedal casing is made of some type of die-cast metal which seems sturdy but the pedal just doesn't operate very smoothy. Several times while playing live the 9V power cable has slipped out of the back of the pedal which created a very loud "popping" noise through the P.A.. I give Line 6 an "A" for effort but a "D" for quality. I will not buy any more of these pedals unless I just want a toy for home use only.
