Unfortunately, I had to return this pedal. The switch is very odd, it did not give me any sensation of I have pressed the button. The LED does light up, but it's not your typical "heavy duty" switch that clicks and punches the floor once you pressed it. I am sure there is many people who loves the soft switch, but this one feels very cheap.
This is only 3 knob pedal, very easy to use and very versatile. It can go from fast slap back sounds to long delays that will keep going - even more sustain with the mash!
Sound-wise I have no issues, it just sounds wonderful. Too bad I could never understand the switch.
The pedal seems sturdy, but you might want to hold it down with velcro, it's very lightweight, one little push to the pedalboard and this little thing has shifted position.
