The Animals Pedal Bath Time Reverb is a standard reverb effect pedal that adds color and depth to the tone of your guitar. You can select three types of reverb sounds and set them according to your taste and song. Use the MIX knob to adjust the balance between dry (original sound) and wet (effect sound). The more you turn this knob clockwise, the more wet it gets, and it sounds like a bathroom. When set to the maximum, the sound will spread from a small attack all at once, creating a beautiful tone that sounds like strings. Use the TIME knob to set the time over which the reverb reverberation will extend. A short setting gives a light reverberation in a small space, and a long setting gives a fantastic reverberation like a cathedral and a vast space like outer space. You can switch the reverb tone with the center toggle switch. The switch positions are from top to bottom, such as the rich hall that resonates in a big hall, the SPRING that reproduces the spring reverb mounted on a large amp, which is often used for classical surf music, and the live house and studio. You can select a ROOM that gives you the impression of reverberation in the space.
