I've been through quite a few delays and reverbs: Delays: Boss DD7 Boss DD3 Visual Sound V2 H2O Ibanez AD9 MXR Carbon Copy TC Flasback Reverbs: EHX Holy Grail I currently have a Boss DD3 and a MXR Carbon Copy I went and tried a new Nano Grail and it did not wow me. So, I took a shot and ordered the EarthQuaker Devices Dispatch Master, it is a Boss Sized pedal that is both a delay and reverb pedal in one. You can do just reverb, just delay, or both. Lately I have been running my amps clean and getting my dirt from either my Fulltone OCD or my Boss SD1 or both stacked in front of my delays. I am not a huge reverb lover, but I do like the ambience of slight delay and slight reverb together. After it arrives I'll post up with my review. My bet is the Boss DD3 gets bumped. Here are the specs: Dispatch Master Delay & Reverb Dispatch Master featured on PremierGuitar.com, recieves Premier Gear award: Read all about it! The smaller and more modern answer to our well loved limited run Ghost Disaster from 2010! The Dispatch Master is a digital delay and reverb unit with an all analog direct signal path and true bypass switching. It is capable of producing nearly 2 seconds of delay time with near-infinite repeats and a cavernous reverb. Both effects can be run separately or in unison. Even though it is a DSP based effect, the sound is warm and full. No sterile lifeless tones here! The delay signal is clear and strong with no after effects or signal degradation and the repeats decay into a nice ambient swell with no oscillation. The reverb is MASSIVE and is sure to please those who love our Ghost Echo but want more depth and less artifacts. The perfect "Black Hole Ambience Generator"! Controls: Time: Controls the delay time, from 0ms to nearly 2000ms Repeats: Controls the regeneration of the delayed signal. Also acts as a enhancer for the reverb. In reverb mode this will control the thickness, decay, depth and overall nature of the reverb. Reverb: Controls the reverb mix Mix: Controls the over all level of the effected signal To use as a reverb only, turn the time control all the way down and adjust the reverb and mix controls to taste. In this mode, the repeats control can be used to enhance the thickness, decay, depth and overall nature of the reverb. With the reverb control at its maximum setting, the repeats control will gradually overload the effect at higher settings. To use as a delay only, turn the reverb control all the way down and adjust the time, repeats and mix controls to taste. To use both effects in unison, adjust all controls to taste. True bypass and hand made one at a time in landlocked Akron, Ohio. Measures 4.37" X 2.37" X 1.75" with knobs Power A standard 9 volt DC power supply with a negative center 2.1mm barrel, no battery option.
