The exact reverb pedal you'd want from DBA! To dial in your sound you have two basic controls: Altitude (triangle symbol) and Verb. Verb controls the amount of reverb (easy enough to grasp!) but the Altitude adds a touch of dirt, noise, and really adds some atmosphere. It's got that clanky/choppy/splashiness of a real spring reverb turned all the way up too. Max it out and you can hear a bit of pitch modulation as well. You can also a change from a darker 'verb to a brighter one via a mini toggle on top. The volume knob is the overall output volume.
