Very high-quality reverb, like all the pedals from mad professor. Its sound ranges from spring, room, and plate reverb. You can adjust the intensity, "depth," duration, and tone, making it dull or bright. It is an extremely "musical" reverb that perfectly complements the guitar sound and does not add noise to the signal. It does not have many different sounds like hall, room, gate, church, like other reverbs, but it perfectly delivers the sound it has. One of the best reverbs in its price range, in my opinion.
