Spring Theory

The SubDecay Spring Theory marks the brand’s first step into DSP, carefully crafted after deep analysis of real spring reverb tanks. Designed specifically for guitar, it avoids generic studio algorithms and instead captures the feel of a true tube-driven blackface spring reverb. It responds dynamically to your playing, with authentic drip, chirp, and vintage surf-style resonance that sounds and feels like the real thing. Beyond its convincing spring mode, Spring Theory also features a powerful room reverb setting, ranging from intimate spaces to vast, cavernous atmospheres. The Reverb knob sets effect level, while Depth controls decay—from natural ambience to endless, immersive soundscapes perfect for lush pads and expansive textures.
