Building 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.

Works great and easy to use
Color: Black
I feel like I’ve finally found a decent milk frother! I’ve gone through (or returned) several models over the last few years, but this one has a different design and hasn’t frustrated me like the others. It has plenty of power to froth milk, foam quality is good, heating is good. I checked the temperature a few times, since a few reviews were critical of that, and it was within a degree or two of what I’d set, so I’d say it’s good! I appreciate that it remembers the last settings so most days are a 1-click operation. But even changing the settings is easy - easier than others I’ve used while having more options.

Best addition to our coffee bar
Color: Black
BEST milk frother we've owned. It is on the larger size but worth it. I love that there are multiple temperature settings. It is easy to use and figure out. The frother spins inside of the stainless steel cup and is magnetically attached inside so it does not come off easily. We use agave for sweetener and being able to throw the cup into the dishwasher to clean off residue has been the biggest plus of this frother. Highly recommend. Worth the cost.

Cute, functional, works great!
I LOVE this thing!! It froths the half and half for my coffee and cream for my tea so beautifully. It's fast, and easy to use and clean. Really adds to my morning routine to be able to choose a temperature and froth level to my coffee creamer. The color is so pretty and both it and the style fit right in with my kitchen decor. I've been using it for several months and haven't had any issues to far. Great item! I was afraid it would just be more clutter and gadgets I didn't need taking up counter space, but it fits right in next to my coffee maker, and I truly do use it every morning. It makes my coffee even more enjoyable, believe it or not. Love it!!

Solid purchase
Color: White, Color: White
I have used it often, basically daily. I love how it has a magnet stirrer and therefore is quiet. I like the stainless steel aspect. It does heat up well. It can store two regular mugs of beverage or maybe 3-4 mugs of froth. It is lightweight but doesn’t feel cheaply made- good enough quality. The froth is great- I have no complaints. I had to learn the hard way that non-homogenized milk gets grainy- weird and icky. I wish it was a little more frothy on the matcha side of things but I still use it. Also, I wish for things like hot chocolate that it got hotter. It goes to 160 on the machine but it doesn’t feel that hot when you drink it. I haven’t measured the temperature of the drink yet but it isn’t hot hot.

It delivered on more levels than I imagined or expected
Color: White
EDIT: I've used this frother pretty much daily, sometimes more than daily, since ordering it, and it has performed very well. I make turmeric/ginger/pepper milk most nights. The way this frother performs for that use astounded me. I bought it for coffee/cocoa/mushroom drinks, then while waiting for it to arrive realized it might work with the "golden milk." First, the little frother uses a closely/precisely applied heat drawing 550w. The thick steel pot nestles down into the heating base, and the cover fits nice and snugly. So I'm not heating an entire thick saucepan perched atop an entire stove burner (1,000-1,500 w), with all the escaped heat that involves. Second, I'm not standing there with thermometer in hand, diving into the open pan of heating milk to find that perfect sweet spot around 150-155...while constantly stirring and making sure not to let it boil over. Because, third, the little frother takes care of that part, with the thermostat auto shut off. Fourth, it whisks the powders smoothly in. Manufacturer suggests starting the whisk movement in the milk, then adding the powders. They did collect a bit in the low vortex around the stem of the little assembly that holds the various whisk/stir/froth blades, but I just stuck a spoon handle in there carefully, and it redistributed easily around the magnetic-driven stirring assembly. And finally, omigosh, the lovely velvety texture! Since these spices express best with extended warming, I'm making one batch, heated and frothed to 160F, then follow that with just milk frothed to 140. While the second batch is running (there's a cool down pause in the process, hastened by rinsing the pot exterior in cold water and of course drying it before putting it on the base), the first batch is steeping the spices...so the combined result is perfect. EDIT: It did its job much faster than I expected (minutes). So I tested it as promised on my "solar generator" backup unit. My thought was that this would make my usual most efficient option for heating milk in those conditions the second most efficient: open saucepan atop a multi-watt-level portable induction cookplace on the 600w setting. And with much less cleanup at a time when water is scarce (electric well pump). We had a power outage here last week. Yep, the 550w frother ran on a Jackery 2000 for the few minutes it took to heat/froth milk--no trouble whatever and hardly put a dent in the charge. WOW. (Technically speaking it could run continuously, continuously heating, for over 3 1/2 hours on a full 2000 kWh charge.) EDIT: This isn't a reduction in stars, just an observation. The frother "tree" assembly that does the business of stirring/whisking/frothing--I thought to order a spare in the event of damage to the original. They are very hard to find online. Maestri House lists the replacement part as "out of stock." Also out of stock, replacement pot and lid. This might be a concern to some considering the tool. But it seems to be well made and I hope gives long service. EDIT: As of May 2026 the little frother is still working exceptionally well on a nearly daily basis. I purchased it in October of 2025, so that shouldn't be a surprise...but just sayin'. :^>
