Death by Reverb - Creating Fun Echo Effects!

Many guitar amplifiers include a built-in reverb setting. Since the 1960s it is one of the most common effects added to electric guitar. These days most reverb is added digitally, but there are some true analog versions out there including Anasounds' spring reverb system (which looks and sounds exceedingly cool!). Most amplifier effects are essentially one knob which adds progressively more reverb creating essentially a larger echo chamber for the sound, but there are other ways to manipulate reverberation digitally to create the illusion of playing in anything from a cave to a large room or even hyperspace if you want to get fairly crazy. Death by Audio's Reverberation Machine is billed as a "synthetic atmosphere creator." Guitar PCB Mania has a version of this circuit called the Death by Reverb which relies on a Belton reverb module for part of the build. It appears to be an "inspired by" rather than an absolute copy, but the controls are fairly similar.
