The MWFX 8 Bit, 1 is a guitar effect pedal that converts the guitar signal into a square wave using an analog, transistor based circuit1. MWFX describes it as responding to the guitar in a similar way to a standard fuzz effect, but with a synthesized tone that falls in pitch as the signal trails out1. In other words, you play it like a fuzz, but instead of clipping the waveform into harmonics, the circuit replaces it with a square wave whose pitch drops as the note decays.
The 8 Bit, 1 is one of a series of re-releases of the original 8 Bit pedal, which MWFX dates to 2007/81. Each of these re-releases is individually handpainted and finished in oak wood1. It carries a list price of £175.002.
What it does to your sound
The 8 Bit does not add distortion in the way an overdrive or distortion pedal does. It converts the incoming signal to a square wave, a waveform with only two levels, which gives the synthesized, buzzy character the pedal is named after. MWFX says it responds to guitar in a similar way to a standard fuzz effect, but with a synthesized tone that falls in pitch as the signal trails out1. That pitch fall is the pedal's signature behavior: as a note decays, the square wave tracks downward, so sustained notes bend away from the pitch you played.
Because the conversion is done by an analog, transistor based circuit rather than a digital processor4, the effect is generated entirely in hardware. The maker refers to the 8 Bit as "our square egg"5.
Controls and setup
The 8 Bit, 1 keeps its external controls to a minimum. Everything else lives inside the enclosure15.
| Control | Location | What it does |
|---|---|---|
| Volume | Exterior | Sets the output level of the effect4 |
| Sensitivity (trigger threshold) | Interior | Sets the level at which the circuit triggers on your playing5 |
| Sample length trimmer | Interior | One of 2 regular trimmers for sample length and sample volume6 |
| Sample volume trimmer | Interior | One of 2 regular trimmers for sample length and sample volume6 |
The interior sensitivity setting is the one to adjust if the pedal triggers too easily or not at all for your pickups and playing style5. The two trimmers set sample length and sample volume6.
With only a volume knob on the outside, the character of the effect is fixed by the circuit. Players who want to shape the sound externally will need to pair it with other pedals, such as an EQ or filter later in the chain.
Guitar and bass use
MWFX states that the 8 Bit suits guitar and bass4. The same claim appears across the whole re-release series4, so bass players looking for a square wave effect can use it as well. For bass, the pitch fall on decaying notes applies the same way it does on guitar, since the circuit tracks the incoming signal rather than being tuned to a specific instrument range.
Where it came from
The original 8 Bit pedal dates from 2007/84. MWFX later re-released the design as a series of individually handpainted units finished in oak wood, each numbered as its own product page: the 8 Bit, 1 here, along with the 8 Bit, 3, 8 Bit, 5, 8 Bit, 15, 8 Bit, 16, 8 Bit, 18 and 8 Bit Pride among others4.
The 8 Bit, 1 is a re-release of the 2007/8 pedal, with each unit individually handpainted and finished in oak wood14. It carries a list price of £175.002.
The 8 Bit, 1 carries a list price of £175.002. MWFX offers the pedal as one of several numbered re-releases in the series78910, each individually handpainted and finished in oak wood.
Handpainted enclosures
Each of the re-releases is individually handpainted and finished in oak wood1, which means no two units share a paint job. The maker's product pages also show handpainted boxes with laser engraving1, and packaging that uses recycled materials1. MWFX describes its pedals as handmade in the UK, established 20083.
Questions
Is the MWFX 8 Bit true bypass?
Yes. MWFX lists true bypass on the 8 Bit, 1 product page, so with the pedal disengaged the guitar signal passes through without the circuit in the way. Like the rest of the 8 Bit re-releases, it carries the same true bypass switching.
Is the MWFX 8 Bit analog or digital?
It is analog. MWFX describes the 8 Bit as converting the guitar signal to a square wave using an analog, transistor based circuit. Despite the name, there is no digital processing involved; the square wave is generated by transistors.
Can the MWFX 8 Bit be used with bass?
Yes. MWFX states that the 8 Bit suits guitar and bass. The pedal responds to the instrument in a similar way to a standard fuzz effect, so bass players get the same square wave conversion and the pitch fall as notes decay.
What controls does the MWFX 8 Bit have?
On the outside there is a single volume control. Inside there is a sensitivity setting that sets the trigger threshold, plus two regular trimmers for sample length and sample volume. The tonal character of the effect itself is set by the circuit rather than by external knobs.
Is the MWFX 8 Bit handpainted?
Yes. Each of the 8 Bit re-releases, including the 8 Bit, 1, is individually handpainted and finished in oak wood, so no two enclosures look the same. The maker also laser engraves the handpainted boxes.
