The Reverb Pro is a control module for spring tanks with the quality and versatility of a studio reverb. In a compact format, the Pro can shape reverberations in a variety of audio production applications and completely change the way you create sound environments. The Pro is a fully analog controller that uses spring tank technology to create the reverberation effect known as spring reverb. To reproduce the analog reverb effect, the Pro needs to be connected to a spring tank. Therefore, we offer different spring tanks of the Accutronics and Belton brands. We offer 6 tank models that will expand your reverberation possibilities. Each model has a sound characteristic that varies according to the length, the amount of springs and the decay.
