The Subdecay Super Spring Theory is the product of truly analyzing the design and physics behind real spring tanks to capture the beautiful nuances of tube driven spring reverb. Use the Tone control to dial in the perfect timbre - and use the internal reverb send trimmer to turn down for hotter input signals, OR turn it up for a more dramatic effect. Use the Decay knob to dampen the string for shorter reverb, or bend the laws of physics resulting in long, psychedelic resonating trails. It features an all analog signal path, with JFET amplifiers carry out the send and recovery of the reverb signal for even more tube-like dynamics. Use it in front of your clean, or dirty amp for ultimate reverb success.
There's also another setting - ROOM reverb! Get the "typical" subject ambient room reverb with the Decay knob dialed back, but it certainly doesn't stop there. The Decay knob will alter the dimensions from a broom closet to a cavern covered in ceramic tile - with reverb trails over three minutes long!
