Does it work? How well does it work? And of course, is it worth it?

My use for it would be trying to lay in a small slap that doesnt completely cover up a bit of solo tapping on the upper frets.

You know like -na na na na BOOM..(then you cant hear anything after the slap T_T-
I use the pedal for every song. it does a great job at balancing out the volume spikes when I slap and it also ( if used right) can be used to up the volume when I tap
you just gotta set the controls just right
but I must say that if you turn the enhance knob past 3 it doesn't sound pretty, but hell I think its worth it for its use of controlling the slapping volume Spike
