Versatile analog stéréo pedal... Actually, there are numerous ways of using it, from the most common tremolo to the more specific one. It's impressive at first sight but quite easy to use. Basically, with such a pedal, we can adapt precisely the parameters and, for instance, adjust the rhythm with our feet—that's what we call the tap tempo. It's so useful I couldn't come back and play without it. Another aspect is the warmth of the sound, that's the special gift of Electro-Harmonix... I'm very fond of it. I recommend this pedal, just try it, listen & you'll probably " hear"...
