But...When I used a fresh 9V 'rechargeable' battery,the sound was very clean, and the effects range quite Broad

I actually asked for a replacement pedal from Amazon because I thought the one I had was broken, but as it turned out, the pedal simply drained the battery after a day of use and two days of sitting

It will literally drain the batteries just by having the input cable in, which is why I gave this four stars instead of five

Dirty, and the battery was left in and it corroded

Excellent battery life too!

Dead pedal, not dead battery

the 9v battery you put inside the sucker will die very quickly although all the Fab pedals seem to do this, I wasn't even using mine and it killed the battery
