This is a decent pedal, does what it is supposed to do. I use it mainly as a volume pedal, but works also a good expression pedal. The rocking movement is quite comfortable and can fit my whole foot, which is nice. However, it is not the most precise volume pedal out there as there is a bit of a lag before it actually affects the volume.
It is quite large, it would not fit all pedalboards, but is bult like a tank and will last a lifetime.
