1、【Versatile Pre-Delay Control】This guitar reverb pedal boasts a terrifying 30ms – 150ms of pre-delay, controllable via the Attack knob. This allows for everything from a quick, rockabilly slapback, to viscous pools of ectoplasmic reverberations, providing a wide range of sound effects to suit your playing style. 2、【Dynamic Sound Depth】The Depth control sets the intensity of the reverb, mixing in the wet signal with the dry. This creates a massive ambient \"depth\" that fattens up the sound, adding richness and fullness to your music. 3、【Infinite Loop Oscillation】The Dwell control sets the length and thickness of the decay, controlling how long the notes reverberate. At the maximum setting, it descends into an infinite loop of self-oscillation, creating a unique and haunting sound effect. 4、【Four Reverb Modes】This pedal features a 4-mode modulation selector knob, offering four different reverb modulation modes. This gives you the flexibility to create a variety of soundscapes, from subtle echoes to dramatic, spacey reverberations. 5、【Boost Switch and Control Knobs】The pedal includes a boost switch for adding gain, and control knobs for Attack and Dwell. These allow you to adjust the pre-delay length, decay length, and oscillation pitch, giving you complete control over your sound.
