The Fishman AFX BlueChorus Mini is a mini chorus pedal made by Fishman for acoustic guitar, carrying the model number PRO-AFX-CH2. A selection switch gives quick access to three chorus effects, Analog, Vintage, and Classic, and a Tone control rolls off high frequencies on the effect only, leaving your direct acoustic tone untouched1. It sits in Fishman's AFX Mini line of acoustic pedals alongside the AFX AcoustiVerb, AFX Pocket Blender Mini, AFX EchoBack Mini, and AFX AcoustiComp Mini.
Three chorus modes in a mini pedal
The Chorus Select switch offers the three voicings, and Fishman describes two of them in its own words. Classic "Adds the depth of a vintage, analog chorus with the sonic clarity of a modern, digital effect." Vintage is "A lush, but crystal clear chorus effect with a nod to bucket-brigade-style designs," the bucket brigade being the analog delay chip design that classic chorus pedals were built on1.
Around the mode switch, three knobs shape the sound:
| Control | What it does |
|---|---|
| Chorus Select | Selection switch offering quick and easy access to the 3 chorus effects: Analog, Vintage, and Classic1 |
| Rate | Sets the overall speed of each effect1 |
| Depth | Mixes the chorus in parallel, adding as much or as little chorus as you want in addition to your direct sound1 |
| Tone | Applies a subtle high frequency roll-off to only the effect1 |
The parallel Depth mix matters for acoustic players: because the chorus is added alongside your direct sound rather than replacing it, the dry pickup tone stays intact underneath the effect1.
Analog or digital?
The BlueChorus Mini is a digital pedal. Fishman lists 32-bit processing and 24-bit A/D, D/A conversion, with a signal-to-noise figure of -100dB and a dynamic range of 100dB1. The Analog mode is a voicing within that digital engine, described by Fishman as bringing vintage analog-style depth rather than meaning the pedal contains an analog chorus circuit1.
Bypass and Dual Path routing
The pedal is true bypass, meaning that with the pedal off, its electronics are literally removed from the signal chain. Fishman also offers switchable buffered bypass for players who prefer a buffer1.
A front-panel Audio Path switch selects the Dual Path routing. Fishman explains that AFX Mini pedals allow you to choose the audio path on which a particular effect will be processed, by flipping the switch. The 1/4-inch TRS input and output are what enable the Dual Path functionality, so a standard mono guitar cable will not engage it1.
Power and connections
The BlueChorus Mini has no battery option: it requires a 9V external power supply, sold separately, drawing 53mA typical. Fishman specifies using its 910-R (120VAC) or 910-U (230VAC) adapter to ensure the published specs, or a suitable filtered and regulated supply with a 5.5mm outer diameter, 2.1mm inner diameter barrel connector, center negative1.
The pedal needs its own 9V supply at 53mA typical, so check your pedalboard supply has the headroom, and use a filtered and regulated output with a center-negative 2.1mm plug1.
Other specifications from Fishman:
- Input impedance: 10M Ohm1
- Output impedance: 1k Ohm1
- Dimensions: 1.9" W x 3.8" D x 1.92" H (49mm W x 97mm D x 49mm H)1
- Enclosure: durable aluminum1
The 10M Ohm input impedance is high enough to sit directly after a piezo pickup without loading it, which is typical of Fishman's acoustic-focused designs1.

Questions
What chorus modes does the Fishman AFX BlueChorus Mini have?
A selection switch gives quick access to three chorus effects: Analog, Vintage, and Classic. Fishman describes Classic as adding the depth of a vintage, analog chorus with the sonic clarity of a modern, digital effect, and Vintage as a lush but crystal clear chorus with a nod to bucket-brigade-style designs.
Is the BlueChorus Mini true bypass?
Yes. The pedal is true bypass, with switchable buffered bypass for players who prefer a buffer. In true bypass the pedal's electronics are removed from the signal chain when it is off.
What does the Tone knob do on the BlueChorus Mini?
The Tone control applies a subtle high frequency roll-off to only the effect, so you can soften the chorus without dulling your direct acoustic sound.
Does the BlueChorus Mini run on a battery?
No. The pedal requires a 9V external power supply, sold separately. Fishman specifies its 910-R (120VAC) or 910-U (230VAC) adapter, or a filtered and regulated supply with a 5.5mm outer diameter, 2.1mm inner diameter barrel connector, center negative.
What is Dual Path routing?
AFX Mini pedals let you choose the audio path on which the effect is processed, selected with a front-panel Audio Path switch. The 1/4-inch TRS input and output enable the Dual Path functionality.
Is the BlueChorus Mini analog or digital?
It is a digital pedal: Fishman lists 32-bit processing and 24-bit A/D, D/A conversion. The Analog mode is a voicing choice within that digital engine, described as adding the depth of a vintage, analog chorus.
