It fixed what i did not like about the pedal. It is exactly what i hoped the pedal would be when i bought it. If you like the hi fi thing the stock one has then leave it alone if you don't try it. I will warn you it is a bitch to do because of the gooping. The circuit board is gooped after the pedal is put together so you have to cut the goop from the side of the encloser. But worth the hour i spent doing it.
