- Lightweight download at approximately 10 MB with no additional authorization required
Description
BMAFB by EXE Consulting is a distortion and fuzz pedal emulator built with three independent stages of amplification and clipping, plus a separate input amplification stage. This four-stage gain architecture sets it apart from typical two-stage fuzz emulations, delivering everything from warm breakup to extreme, wall-of-noise fuzz tones.
The plugin was developed using RackAFX, based on the audio DSP techniques described in Will Pirkle's textbooks on audio effect design. Each clipping stage adds progressively more harmonic complexity, producing a heavily saturated and compressed tone characteristic of classic fuzz circuits.
BMAFB excels at very high gain settings where the cascaded stages interact to produce thick, sustaining fuzz. For the best results, pairing it with a clean or low-gain amp simulator is recommended, as running it into a high-gain amp can push the signal into uncontrollable feedback and squealing.
Users praise the plugin for its authentic fuzz character and sonic flexibility. The tone captures what many describe as the definitive fuzz sound with rich harmonic overtones that respond dynamically to playing input.
The plugin ships as a VST3 file for Windows in both 32-bit and 64-bit versions, with the VST3-to-VST2 rename trick available for hosts that require the older format. The download weighs approximately 10 MB.
Frequently Asked Questions
How does BMAFB differ from BMBF?
BMAFB and BMBF are both fuzz pedal emulators from EXE Consulting, but BMAFB has three stages of amplification and clipping while BMBF has the more common two stages. This gives BMAFB a noticeably heavier, more saturated distortion character at identical knob settings.
Why does BMAFB produce a high-pitched squeal at extreme settings?
At very high gain and feedback settings, the three cascaded clipping stages can create a runaway feedback loop that produces a piercing squeal. The developer recommends feeding BMAFB into a low-gain amp sim like LG2Amp, especially during live playing, to keep the output manageable.
Can BMAFB be loaded as a VST2 plugin?
Yes. Renaming the .vst3 file extension to .dll causes most hosts to load the plugin as VST2. However, the developer notes that saved projects may not reopen with correct parameter settings when using this method, so VST3-compatible hosts are recommended.
Is BMAFB suitable for bass guitar or synths?
While BMAFB was designed as a guitar fuzz pedal emulator, its extreme gain range and harmonic richness make it useful for adding aggressive distortion to bass guitar, synths, and drum buses. Pairing it with a clean amp sim helps tame low-end rumble on non-guitar sources.
