The MojoHandFX Bayou is a tremolo pedal built to reproduce the amp-style tremolo of older tube amplifiers, the kind of pulsing volume swell that players once got from the tremolo circuit built into an amp. MojoHandFX describes it as designed to faithfully reproduce that classic amp-style tremolo, with an all-analog audio path and true bypass switching. It lists for $149.00 USD as of 25 October 20261.
What it does to your sound
The Bayou sits in the tremolo pedals family: it varies the volume of your signal rhythmically, rather than shifting pitch the way a vibrato pedal does. MojoHandFX frames it as an amp-style design, meaning it aims for the straightforward volume-based wobble of a vintage tube amp tremolo rather than a more heavily processed effect1.
The maker also points to a second use: with the DEPTH control at 0 and the LEVEL set to a fair amount of boost, the Bayou gives what MojoHandFX calls "a wonderfully unique kick to the tubes" without overly coloring the signal, and at low RATE settings it produces a barely audible, almost vibe-like quality. In that role it overlaps with what a dedicated boost pedal does, with the option of motion behind it1.
Controls
The Bayou keeps things to three knobs, plus a pulsing LED that shows the speed of the effect1.
| Control | What it does |
|---|---|
| RATE | Ranges from slow warble to full-tilt flutter; the status LED mirrors the rate1 |
| DEPTH | Offers everything from a light and buttery shimmer to a deep pulsing throb1 |
| LEVEL | Makes it simple to find unity volume, and can give a significant boost1 |
The pulsing rate LED is worth a note for live use: because the status LED mirrors the RATE setting, you can dial in the speed of the tremolo with the pedal muted or before it is audible in the mix1.
Power and size
The Bayou runs on a standard center negative 9V DC supply or a 9V battery, though MojoHandFX includes neither with the pedal. Current draw is approximately 10mA, low enough for any standard pedalboard supply1.
A 9V battery is supported but not included, and the same goes for the power supply. Budget for both if you are adding the Bayou to a new board.
At 4.8" long by 2.62" wide by 1.55" tall, it takes up a compact footprint on a board1.

Questions
Is the MojoHandFX Bayou true bypass?
Yes. MojoHandFX lists the Bayou as true bypass, so when the pedal is off your guitar's signal passes through without the circuit loading it. That matters on a pedalboard where several pedals sit between the guitar and the amp, since buffers and non-true-bypass designs can each add a little color to the tone.
Can the MojoHandFX Bayou run on a 9V battery?
Yes. MojoHandFX says the Bayou runs on a standard center negative 9V DC supply or a 9V battery, though neither is included with the pedal. With a current draw of around 10mA, a battery lasts a long time, and the pedal is also easy on any standard pedalboard power supply.
How much current does the MojoHandFX Bayou draw?
MojoHandFX lists the current draw at approximately 10mA. That is low enough to share power with other pedals on most daisy-chain supplies and small enough that a 9V battery is a practical option.
Can the Bayou be used as a clean boost?
MojoHandFX says that with the DEPTH control at 0 and the LEVEL set to a fair amount of boost, the Bayou gives a kick to the tubes without overly coloring the signal. At low RATE settings the maker describes a barely audible, almost vibe-like quality, so it can sit in a rig as a boost with a subtle motion behind it.
How big is the MojoHandFX Bayou?
The Bayou measures 4.8 inches long by 2.62 inches wide by 1.55 inches tall, according to MojoHandFX, so it fits a standard pedalboard footprint without crowding.
