The EarthQuaker Devices Ghost Echo is a vintage-voiced reverb unit designed to emulate the haunted, atmospheric character of classic amp-top spring tanks. This analog/digital hybrid circuit utilizes a unique pre-delay range of 30ms to 150ms to create everything from subtle room ambiance to deep, cavernous echoes. By separating the initial attack from the reverberated signal, it allows for distinct slapback tones that remain articulate during fast playing. The current V3 iteration features upgraded op-amps for a lower noise floor and a recalibrated dwell control capable of reaching self-oscillation. A specialized collaboration with the creative studio Brain Dead resulted in a limited edition version featuring custom psychedelic artwork.
