Walrus Audio Monumental Harmonic Stereo Tremolo BlackBuilding off the rich, warm, pulsating modulation of the Monument, the Monumental Harmonic Stereo Tremolo 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.
New Features
• True Stereo Input/Output
• The ability to save and recall three on-board presets, as well as a “live” mode
• Full expression control over every parameter
• An additional wave shape and tap division
• Pan control to allow the tremolo to sweep from left to right
• S-B-H to allow the user to blend from standard to harmonic tremolo modes
• The ability to ramp up OR down (ramp location controlled via rate control) to achieve “Leslie” style ramp from your current rate
Inspired by the beautifully jagged, red-sand desert landscape of Monument Valley, the Monumental Tremolo is capable of blending between harmonic and standard tremolo to produce 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.
With different combinations of stereo panning, rate, division, and wave shapes, 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 highpass 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.
Controls
PAN: Control the stereo spread of the left and right channels. 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.
S-B-H: Use this control to blend between standard and harmonic tremolo modes. In standard, all frequencies get affected at the same time. In harmonic, the high and low frequencies are offset from each other - When high is on, low is off and when high is off, low is on.
Pro Tip: Blending between standard and harmonic with the PAN knob turned up past 0 creates interesting polyrhythmic sounds.
PRESET: The Monumental has three onboard presets with an additional live mode. Each preset can save and recall every parameter available on the pedal. Press both the bypass switch and tap tempo switch simultaneously to cycle through the available presets (Red, Green, Blue, with White being “live”).
When you are on a preset and you change a parameter, the bypass LED will change color to purple, indicating a change has been made. You can then turn the control and the bypass LED will return to the preset color when the control is at the saved position. Once you have determined what sound you want saved for the preset, hold down both footswitches to save the preset (the bypass LED will return to the preset color).
Live mode will always return to the current knob positions on the face of the pedal.

Great buy
Color: Blue+Red
My dogs kill every toy. They arrived very agressive chewers. These have lasted way longer than most balls have. Great value

If your dog loves tennis balls, you NEED these
Raising any puppy is tough. Raising a German Shepherd puppy has often left me questioning my life choices. So I was ecstatic the day that my 60-lb puppy decided that he loves tennis balls and occupied himself for 2 hours without needing constant intervention. Naturally, my immediate response was to make sure we had a constant supply of large tennis balls for dogs available. Now my puppy loves mischief, but he’s not an aggressive chewer. And I was irritated to discover that every brand and size of tennis ball broke within an hour max of play. By simply playing fetch and batting the ball around with his paws, every single tennis ball split into 2 halves. We needed something better!
These squeaky balls are exactly that! They come in a 2-pack. I gave my pup the 1st one a week ago and it’s still going strong! We play fetch in the backyard, he brings it into the doggy pool with him, it rolls around in the dirt and can be rinsed off easily. It’s by far his favorite toy, and he takes it everywhere with him. Finally a squeaky ball that can keep up with my dog! These are the perfect size, texture, bounce, squeak, everything. These are the ONLY squeaky balls I will buy from now on. Five stars for sure!

Durable squeaky ball for chewers
Color: Blue+Red, Color: Blue+Red
These are great! My 54 lb GSP loves them and it’s the only thing she cannot destroy! She’s currently 1 year and we have had the balls for several months. We have this brand and similar ones too. They float, bounce, and squeak. The ridges are good for chewing.

Great squeaky balls
Color: Blue+Red
Awesome! My super chewers haven’t been able to destroy it. It’s been about 3 months now and it still squeaks and bounces like new! It’s a bit tougher than normal squeaky toys but so worth it for aggressive chewers.

My Doxie’s Absolute Favorite Fetch Toy – Who Knew Baby Balls Could Be So Paw-some?
I bought these colorful baby balls as a simple toy for my little one, but my furry bay claimed them as his own from day one! These small, bouncy balls are perfect for little dogs – they’re lightweight and easy to grip in his mouth, keeping him entertained for hours. No squeakers or stuffing to destroy, just pure, durable fun. If your pup loves a good game of fetch or just batting things around, these “baby” balls are a steal. Highly recommend!
