All tremolo pedals should have a tap tempo, it's just such a great function on a trem. This one sounds terrific; you can dial in all sorts of delicious wobbly goodness. Plus, you can save presets, control them via MIDI, change any parameter ob the fly via expression pedal... it's very tweakable. It'll chop you up in all the right ways.
