From Atmosphere to the Vast Depths The EarthQuaker Devices Ghost Echo V3 reverb pedal is one to think about for players looking for a powerful but easy-to-use verb. The Ghost Echo V3 is based on vintage spring reverb units, but some simple tweaking delivers hall-type sounds as well. The attack knob dictates when the effect enters your signal for note clarity, and it can even simulate a slapback delay. And the 100% analog true-bypass construction ensures you're getting your truest guitar tone. This third-generation editon of Ghost Echo V3 boasts upgraded op-amps for better sonic performance, a stronger reverb signal with double the output, and a re-calibrated Dwell control that can reach self-oscillation. It also features updated artwork and silent, relay-based switching.
