Strymon Flint Tremolo & Reverb Guitar Effects Pedal
The Strymon Flint is the best tremolo pedal in 2023. The Flint offers high-quality effects in both categories, unlike the majority of multi-effects pedals. Basically, it’s two pedals in one. The Strymon flint pays homage to some of the best renditions of each effect with three adjustable presets for the tremolo and reverb channels. Controls on both channels are interconnected and interdependent, and they can significantly change how your guitar sounds. Additionally, the use of dual outputs opens the door to the use of two amplifiers.
It should come as no surprise that Strymon’s developers enjoy vintage tones themselves. A variety of their favorite sounds are represented by the Flint’s reverbs, which include a dual-spring tank from a 1960s tube amp combo that will sound instantly familiar to guitarists, an electronic plate reverb from the 1970s with lots of shimmer and clean tails, and an 80s digital rack reverb for intricate, modulating reverberations. The three tremolos on the Flint are based on three amp circuits from the 1960s: a hard-edged photocell tremolo, a dazzling and gritty power tube tremolo, and a rare gentle and pulsating harmonic tremolo.
Walrus Audio Monument V2 Harmonic Tap Tremolo Guitar Effects Pedal
- 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...
- Improved tremolo response across all Rates
The Walrus Audio Monument V2 harmonic tap tremolo effects pedal offers a wide variety of tremolo styles, as well as a Tap tempo switch for hands-free tremolo rate control. The tremolo rhythm can be precisely tailored for any purpose using four distinct time division settings. You can experiment with trem effects ranging from smooth and subtle to hard-chopped staccato using five distinct waveshapes: sine, square, ramp, lumpy, and random. The Walrus Audio Monument V2 is one of the most comprehensive tremolo pedals you’ll discover, with a harmonic tremolo mode for vintage rhythmic delicacy.
The first setting is a chewier setting modelled on Fender’s “brownface” amps, while the latter produces a more typical amp-style wobbling. A separate tap tempo footswitch (with division knob) is included, as is a temporary bypass feature and a full wave control that includes sine, square, ramp, lumps, and a random Monument Mode.
The input and output jacks on the Monument are positioned on the top of the enclosure in a pedalboard-friendly way, allowing room for an expression-pedal input socket. While this may be used as an auxiliary tap-tempo switch (by flicking a switch inside the pedal enclosure), it’s hard not to think of it as a bit of a pity in comparison to the world of temporal delight that opens up when you add an expression pedal. It’s worth noting that there were jack sockets for both of these options on the prior, larger generation of this pedal. This is the best tremolo pedal in 2023.

Chase Bliss Gravitas
- Famed Analog Devices AD823 opamps
- Stays 100% analog
- Discrete class A clean boost circuit
The Chase Bliss Gravitas is a tremolo pedal with an all-analog signal path that can do any kind of conventional volume modulation, harmonic tremolo (influenced by old Brownface), or both at once for a genuinely distinctive and lovely tremolo sound that fits just right in a mix. Your guitar’s signal path is opened by a stunning, transparent, distinct class. For the best tonal clarity and analog warmth, a clean boost circuit is followed by buffering and tone shaping using renowned Analog Devices AD823 opamps.

Frequently Asked Questions
What is a Tremolo pedal?
Tremolo pedals, in essence, alter the loudness of your guitar’s signal on a regular basis. It uses a variety of chops and wobbles to create unearthly sounds that are often difficult to control.
To alter the pitch, guitarists frequently use a “tremolo arm” or a “vibrato arm” on the guitar. The arm and the pedal both produce rhythmic effects, although they do so in distinct ways. Both approaches, however, are difficult to master; prior expertise is required. Tremolo pedals produce evocative soundscapes. Marc Ribot, Johnny Mar, Johnny Greenwood, Tom Morello, Duane Eddy, and Dan Auerbach are all big fans of these pedals.
How does a Tremolo pedal work?
A tremolo pedal produces a simple modulation effect by changing volume levels to produce rhythmic shifts. They rapidly increase and decrease the volume level.
The rate and shape of the wave oscillations can be changed to achieve a variety of effects. They do this in a variety of methods, but the most common is to use a Low Frequency Oscillator (LFO), which generates a waveform for volume changes. LFOs work at frequencies between 0 and 20 Hz that are inaudible to the human ear. With their rounded form, sine waves create a strong tremolo, whereas triangle wave patterns create attention-getting peaks, or even rises and dips in music.
In recent years, we’ve seen square waves that, if the depth is maximized, can entirely deaden the sound signal. Tremolo effects are generated by battling volume and frequency, and it is one of the most extensively used modulations by electric guitar players across numerous genres. The volume rises and falls more slowly with less regularity, resulting in a slower effect.
With a higher rate control, we get significantly more staccato percussive sounds, which have been described as jagged, metallic, or even machine gun-like. Tremolo types are classified according to their bias (in reference to the age old preference towards vacuum tube-amps.) The term “optical tremolo” refers to a circuit used in original Fender amplifiers that employs a photo cell or “optocoupler.” This is a light-dependent resistor with a smooth wave created by altering the resistance within it.
Where to place Tremolo Pedal in a pedalboard?
The optimum place to put it will depend on the type of pedal board you have and, of course, the different types of tremolo. Typically, your tremolo should be placed near the end of your amp circuit since you want the overall volume modulations to apply to everything you’ve configured.
This should ideally include reverb as well, but some guitar amps have built-in tremolo and reverb, so you won’t be able to control it unless you have a reverb pedal on your pedalboard. This ‘vintage’ signal flow at the conclusion of the chain enables for the best use of tremolo, which in its most subtle form will be lost if compressed. Technically, if tremolo is put before delay pedals, especially high rates that cause dramatic modulations, loudness changes are also reduced.
