The Spirit Box is a reverb unit inspired by the EQD Ghost Echo. It is powered by an Accutronics “Belton brick” and offers a wide range of reverb sounds, from subtle spring-like tones to deep, cavernous reverbs. The controls on the Spirit Box allow for versatile sound shaping. The Attack control adjusts the length of the pre-delay, while the Dwell control determines the length of the decay (with feedback being normal at extreme settings). The Depth control allows for adjusting the wet/dry signal mix.
