Product Description

Walrus Audio’s Monument pedal offers the full spectrum of tremolo goodness – from classic velvety wobble to resonant overtone shimmer. With the V2, they’ve shrunk the form factor to single-pedal size, added top-mounted jacks, external tap & expression connectivity and a drastically improved frequency response.

The Walrus Audio Monument V2 – what’s new?

  • Converted to smaller enclosure
  • Expanded capability of side jack: now supports external tempo or can function as expression control over Rate, Depth, Shape, or Tap Multiplier and is assignable on the fly
  • Improved tremolo response across all rates
  • Top mounted jacks
  • Momentary switch for instant effect toggle on/off

Here’s what Walrus Audio say:

Inspired by the beautifully jagged, red-sand desert landscape of Monument Valley, the Monument Tremolo is both a harmonic, and standard tremolo that produces a rich, luscious, warm pulsating modulation capable of peaks and valleys as smooth or as jagged as the real ones that our dear mother nature created long ago.

Full Tremolo Palette 

With different combinations of the rate, division and shape knobs and tap tempo, everything from traditional tremolo to inspiring unique waveforms will help you carve new paths that you won’t hear anywhere else.

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 180 degrees out of phase (high and low frequencies rise and fall opposite of each other). The result is a warm, almost “chewy” tremolo.

The Division knob can be set to quarter, triplet, eighth and sixteenth. Wave shapes can be controlled via the Shape knob. You can move between Sine, Square, Ramp, Lumps and Monument Mode (random).

Momentary Switch

A special feature on the Monument is the bypass switch also has a momentary function. When the switch is in off position, press and hold to temporarily activate the effect to add a moment of texture. Releasing the switch turns the effect off.

When the pedal is on, press and hold the bypass switch to ramp up the tremolo rate. Release the switch and the rate will ramp down to previously set tempo. Setting the depth knob at 0 and the volume knob above unity creates a clean boost.

My new favourite wobble box. I think this is a new aways-on pedal in at least some subtle way. Just adds a little bit of extra interest to sustained notes/chords. Very versatile with a lot of options for sounds and the ramp up foot switch is a fun extra feature

An excellent and versatile tremolo pedal. Variety of modes, boost to compensate for perceived volume drop, tap tempo, small footprint, and pretty graphics.

Great sounding tremolo with some great options to personalise, such as harmonic or amplitude modes and various wave forms to choose from, not to mention tap tempo which is always handy.
