The Ghost Echo is EarthQuaker's spooky take on the haunted* amp-top spring reverberation units of yesteryear. This creepy analog/digital spring reverb emulation machine boasts a terrifying 30ms – 150ms of pre-delay, controllable via the Attack knob, for everything from a quick rockabilly slapback to viscous pools of ectoplasmic reverberations. When playing staccato, you’ll hear the tortured trails of the reverb, resulting in more of a slapback or echo sound. Legato playing will reveal a massive ambient “depth” that fattens up the sound – and look out, it’s right behind you! Phew, that was close. The Dwell control sets the length and thickness of the decay, which is to say that it controls how long the disembodied spirits of notes no longer with us float through the ether. At the maximum setting it will descend into an infinite loop of self-oscillation. The Depth sets the intensity of the reverb, which you probably know as the wet/dry mix, but we like to think of it more as how scary the overall effect is. Tech Specs Measures: 4.75 x 2.50 x 2.25 with knobs Current Draw: 86mA Input Impedance: 10M Ohm Output Impedance: 1K Ohm Switching This device is true bypass and uses electronic relay-based switching. Audio will not pass without power. *Not actually haunted. Or are they?
