The R1 is an extremely powerful and versatile multifunction reverb with six customized, studio-quality programs - Spring, Hall, Plate, BFR, RFRCT (Refract), and Air. Every program has the option to be tuned and tweaked from short and subtle room sounds to massive washes of experimental euphoria. The R1 is your architect for new songs and textures to create and inspire.

REVERB PROGRAMS Spring - The Spring program emulates an excited spring reverb commonly found in tube amps with loads of bouncy drip. Easily go from subtle to full-on surf rock and beyond. Experiment with the decay knob to get more than normal amounts of reverb not found in traditional amp spring reverb tanks. X knob adds a gentle, warm overdrive to the reverb input simulating overdriving the spring tank. Hall - The Hall program provides the acoustics of large live sound spaces like concert halls to arenas.
CONTROLS Decay - The Decay knob sets the length of the reverb decay. Set this control low for short natural sounding decays or higher for longer more ethereal sounding reverbs. Swell - The Swell knob engages a volume envelope applied to your wet and dry guitar signal as it passes through the R1 creating a gentle volume swell. This helps create unique moments of cinematic ambiance. The position of the Swell knob determines how long it takes to fade in the guitar and reverb signal after you play.
CONTROLS Prog (Program) - The Prog knob selects the desired R1 delay program. See the Program section for more details about each reverb program. Tune - The Tune knob and switch offer creative control over three additional parameters that allow further shaping of each reverb program. Simply move the toggle below the knob to select the parameter you want to control, then use the Tune knob to dial in the right amount of Lo, High, or X.
Bypass LED - Indicates if the pedal is on or off by illuminating solid when on, and off when the pedal is off. Sus/Latch Switch - The Sus/Latch switch allows you to momentarily sustain the current reverb sound by pressing and holding on the switch. You can also latch the sound by clicking this switch on and click again to unlatch.
o To recall a preset: 1. First, select the bank of presets you want to access with the A|B|C switch. The pedal will automatically recall the red preset in that bank. 2. Next, scroll through the presets in that bank by pressing both stomp switches at the same time. Each press of both stomp switches will load the next preset until you get back to red and the pattern repeats. o To save a preset: 1. First, recall the preset in which you would like to build a new sound. 2.
MIDI The R1 is able to be controlled via standard MIDI messages. Simply connect your MIDI controller to the R1 MIDI “IN”. Downstream MIDI devices can be connected to the MIDI “THRU” which simply lets all incoming MIDI messages pass through to your other devices. The R1 ships with the MIDI channel set to 1 by default. o To assign the MIDI device channel: 1. Hold down both stomp switches at power up then release once the LEDs begin flashing white. 2.
