[Edited/Updated | This post has been updated to reflect several months of use, as well as a recent A/B comparison with the EQD Levitation w/ review: NPD: EQD Levitation] Famous last words - this pedal represents the last piece of the puzzle (setup). Seriously ... I am sure that I will continue to play around, swapping new pedals in and out BUT since I have no more space on the board itself and I have all the bases cover, I am very content with the current configuration. I find Reverb to be an effect where achieving the desired settings is a very nuanced process so, unlike a distortion pedal, it's not as if I plugged in the guitar and started to go crazy, amp-to-eleven, rock'n'roll all night long. The process of playing around with the settings and listening to the resulting effect tones was much more methodical. The EQD Ghost Echo, with a "Spring Reverb" inspiration, has great versatility built upon that foundation. One can get surf-like spring, country tone slapbacks, ending up all the way to very water-filled-cave depths. Sometimes I swear I can hear the echo of water dripping within the effect. The different controls, while limited (maybe better thought of as "focused") let the user dial-in the perfect blend and nature of reverb. I originally had used the term TONE when I first posted this review but there is actually no Tone control on this pedal. That being said, the voice of the pedal successfully passes through the full-body nature of the dry signal giving the effect a very warm and organic feel (think: mids are well represented in the mix but no part of the EQ spectrum is over saturated or emphasized.) The Depth and Dwell knobs feel like they work in tandem to fine-tune the resulting nature and length of the effect; defining the environment. This level of control just adds to the versatility in the sense that the effect can be used in more situations when otherwise, without the control, it could have been either too little or overpowering. As a tinkerer, I find myself always fighting the urge to fuss around with the settings of any pedal instead of just leaving things "as is". That said, the reverb pedal often works best either being on/off, depending on the need, with just slight adjustments to the settings - an attribute that the Ghost Echo excels at. What has been shared by many users, a perspective I can identify with, is that once I found the right/subtle amount of reverb, I just leave the pedal on and untouched for most of the time. On occasion, when needed, I dive into the deep-end of the pool and explore the infinity caverns hidden within the Ghost Echo. The Attack Knob provides the ability (while limited) to pull the dry guitar tone out and in front of the reverb effect. This is great for more percussive playing (think: reggae/rock/ska - Marley, Police, etc.) The more intense the effect, the dry tone will almost get completely washed over - left just at the cusp of gasping for air. Hidden qualities: While I tend to keep the pedal very tame, there are occasions where I greatly increase the intensity of the depth & dwell settings at which point I am able to achieve a very crystal-like resonance/feedback in the trails of the effect -- much like wet fingers being rubbed across the top of a crystal glasses filled with water. White Noise: As others have mentioned, there have been occasions( depending) when I have heard a bit of background "white-noise" when the effect reaches it more saturated settings AND with the absence of any playing. Once I start to play, the music masks any of the noise. I don't want people to read too much into this as I don't think it detracts from the pedal ... it is the same sort of noise that one would hear when powering on the amp before playing the first note - you know it is on and alive but given a few moments, it just sort of blends into the environment. One might even argue, with validity, that an expansive/cavernous environment will have a similar sort of ever-present reverberated sound of "space". Just to reiterate, I only hear this on occasion when the effect is at the high-end of its settings. Finally, as requested, I have included pictures of the Glow-in-the-Dark paint job. Just note: it took a UV Black-light to pull this off. More modern LED or Florescent Bulbs seem to be more challenged in "charging" up the glow effect. Being that is was the same price, I thought the limited-edition was cool and since I have a black pedal board, it stands out more than if the pedal itself was black.
