Clone board of the Spaceman Effects Orion reverb. Great sounding reverb, in a convenient pedal format. Using the Accutronics blue reverb tank, and silent switching, it makes for a great portable reverb unit that you can use anywhere, with any amp.
NOTE: Be aware that at the end of the day, this is still a spring reverb, so if you go at it hard enough, you will get the customary spring crash. Please follow the build recommendations in the build document to avoid this. Unless crashing spring reverbs is your thing... then carry on.
