This pedal has everything you want it to do. It take a little tweaking and it will work right. Forget trying to change the battery just buy a power source. I had to have it modded to True Bypass because this thing makes your tone go south even when its off.

This pedal works EXACTLY as described in the Commentary on the site, i haven't had any problems with it at all. It's even powerful enough to be used as a noise gate depending on how much gain you're using. I would recommend this effect over any enveloped wah i have ever heard. the only thing i don't like is that the closing of the gate is at the same speed as the opening.
