Used Subdecay Spring Theory Pedal

Notify me when this product is available:

Pre-owned Subdecay Spring Theory with box. In Good condition, scratches all over, rubber feet on back.


For our first foray in to DSP we put our white lab coats on, we listened to a lot of reverb, and then we listened some more. We tore apart reverb tanks to see what makes them unique and created something truly special.

The Spring Theory is designed specifically for guitar. You won’t hear a supposed spring reverb simulation that just doesn’t cut it, or some so-called “studio” reverb designed for vocals or drums ported to a pedal format as an afterthought.

Sounds like the real deal!

The Spring Theory sounds and feels like a real tube driven black face reverb. It reacts dynamically to the attack of every note you play. You can hear the springs chirp and resonate. Vintage wet surfy reverb sounds that are only found in amplifiers and stand alone spring reverb units… Until NOW!!!

Oh, and we haven’t even mentioned that other setting. Not only did we create a great authentic spring reverb pedal, but we also created a very special room reverb. The room setting simulates anything from a small space to a 10 mile wide cavern with ceramic tile on every surface.

The reverb knob sets the effect volume. The depth knob controls the reverb length. Set the depth knob near the middle for realistic lush sounds. Turn it to the right for unrealistic everlasting reverbs. The room setting is especially awesome for this for creating synth like pad sounds and thick, rich sonic landscapes.

The Spring Theory can be powered by AC adapter only. There is no battery option for this pedal.
