R1 is a powerful and versatile multi-function reverb with six customized studio-class programs: Spring, Hall, Plate, BFR, RFRCT (Refract), and Air. From subtle room reverbs to space-filling experimental and dreamy reverbs, the wide range of sounds will inspire you to create new songs and phrases. [Main features] ●6 distinctive reverb programs Spring This program emulates the "springy" spring reverb found in classic tube amps. Easily create anything from a subtle spring sound to authentic surf rock tones and even more extreme tones. The X knob also adds a touch of warm overdrive to the reverb input. Hall Simulates the acoustics of large venues such as concert halls and arenas. Depending on the settings, you can create anything from a flood of reverb to the reverb of a small space. Plate This reverb program emulates analog plate reverbs with a smooth, even spread, and is based on famous plate reverbs such as the EMT 140 by Elektro Mess Technik. BFR Big, fxxking, reverb. A hall-style reverb that's richer and decays more than a massive arena reverb, echoing like a vast cavern filled with a choir of angels. Rfrct (Refract) A beautiful and charming glitch reverb floating above a vast reverb. Air This spacious reverb mode adds a slight shimmer, and features a clearer tone for the decay. It can also create a slowly rising shimmer sound that won't get in the way of your playing, and can also create keyboard or synthesizer-like tones. ●Presets There are nine onboard presets, three banks A, B, and C, with three in each bank, and up to 128 presets can be saved and accessed using MIDI. ●Three bypass modes The R1 has three different bypass modes:・True Bypass DSP+True Bypass (trails)・DSP Bypass (trails) Power supply: 9VDC center negative (for adapter only) *300mA minimum ■SIZE: 12.6 x 7.3 x 6.2 cm
