Walrus Audio Monumental  is an analog, optical tremolo bringing new controls, features, and width to the Walrus Audio line.

New features available in the Monumental include the ability to save presets, blend between standard and harmonic tremolo modes, access to new wave shape and tap division options, and most importantly, a pan control to set the stereo spread of the tremolo to the right and left channels.

Harken back to vintage tones inspired by Fender Brownface amps in Harmonic mode. A low-pass and high-pass version of your guitar signal is modulated opposite of each other, or 180º out of phase (high and low frequencies rise and fall opposite of each other). The result is a warm, almost “chewy” tremolo. Turn the S-B-H counterclockwise to give more bite to your tremolo pulse and tame the out-of-phase harmonics.

Control the stereo spread of the left and right channels with Pan. Counterclockwise is your standard tremolo sound, the left and right channels have the same LFO. Turning the control clockwise will offset the phase of the right LFO to introduce stereo spread. Fully clockwise is maximum panning with the right channel LFO being 180 degrees out of phase from the Left LFO.

Use the S/B/H control to blend between standard and harmonic tremolo modes. In standard, all frequencies get affected at the same time. Blending between standard and harmonic with the PAN knob turned up past 0 creates interesting polyrhythmic sounds.

The Monumental has three onboard presets with an additional live mode. Live mode will always return to the current knob positions on the face of the pedal.

The pedal is available in black and red and is powered by a standard 9 volts power supply (not included). For more headroom you can also use a 12 volts power supply.
