A major evolution in ultra-high-performance reverb The R1 MKII is an incredibly powerful and versatile multi-function reverb with six customized studio-class programs: Spring, Hall, Plate, BFR, RFRCT (Refract), and Air. All programs offer a wide range of sound options, from subtle room reverbs to space-filling, experimental, and dreamy reverbs. The R1 will inspire you to create new songs and phrases. ---------------------------------------------------------- Power supply: 9VDC center negative (for adapter only) 300mA minimum [New Features] - All six programs have been redesigned for significantly improved sound quality. -New ducking/swell feature.・SIZE (acoustic space size) control. *In RFRCT, this sets the particle delay time. -Diffuse control. - Feedback EQ control. - 128 onboard presets accessible via menu. - OLED display for easy adjustments and preset management. PROGRAMS Spring Spring emulates the "springy" spring reverb found in classic tube amps. Easily go from a subtle spring sound to authentic surf rock tones and even more extreme tones. Try twisting the Decay knob to explore experimental sounds beyond the reach of traditional spring reverbs. Hall Hall simulates the acoustics of a large venue like a concert hall or arena. Set the right encoder to a long decay and a high size to create a flood of reverb. Set the right encoder to a short decay and a low size to create a small reverb sound. Plate Plate is inspired by famous plate reverbs like the EMT140 (ElektroMess Technik, Germany) and emulates an analog plate reverb with a smooth, even spaciousness. BFR BFR is big, fxxking, reverb. This is more than a giant arena reverb; it's a rich, decaying hall-style reverb that echoes through a vast cavern filled with angelic choirs. Refract RFRCT produces a granular delay module with a controllable amount of reverb, resulting in beautiful, captivating, glitchy textures. The DIFFUSE control allows you to set the amount of reverb from dry to heavily diffused. The RATE control below the left encoder sets how often new grains are generated. The DEPTH control sets the modulation applied to the grains, including reverse, grain regeneration, and modulation. Air The Air program is a spacious reverb mode with a slight shimmer, giving it a clearer tone over the decay. Look for a shimmer sound that builds slowly without getting in the way of your playing. It can also create keyboard or synthesizer-like tones. PRESETS The R1 MKII has a total of 128 preset slots. To access a preset, press the left and center encoders simultaneously. The first nine presets can be selected from banks A/B/C and accessed directly from the pedal using the BYPASS and TAP/SKIP switches to toggle between presets. All 128 presets can be accessed via MIDI program change messages.
