The MBD4 Black Friday deal from Audio Blast takes 60% off this four-band distortion and compression plugin, bringing it to $27 until Nov 29, 2026.
MBD4 splits your signal into four bands and puts a compressor and a distortion stage in each one. You pick the character per band, so the low end can stay clean while the mids get harmonics.
It works as a multi-effect plugin for bass, drum buses, vocals, synths and guitar.
Three adjustable crossovers divide the signal into LOW, LOW MID, HIGH MID and HIGH. They are 24 dB/octave Linkwitz-Riley slopes.
Every band can use any of the 32 distortion models, or OFF. That lets you thicken a guitar in one region and add a digital edge up top.
Band SOLO and BYPASS controls let you hear what each band is doing before you go back to the full signal.
The maker groups the 32 models into families:
DRIVE / REDUCE sets intensity, DIST MIX blends the effect within the band, and DIST OUT balances the level.
Each band has its own routing switch. With PRE, the distortion comes before the compressor, so the compressor reacts to the harmonics the distortion creates.
With POST, the distortion sits after compression and makeup gain. The compressor tames the incoming dynamics, then you drive the result into the model.
You can run PRE in one band and POST in another.
Each compressor has threshold, ratio, attack, release, knee and makeup gain. Detection is stereo-linked, so the same gain reduction hits left and right within a band.
For compression without distortion, set the distortion menu to OFF. For distortion without gain reduction, set the ratio to 1:1.
A global DRY / WET control blends the whole processed signal with the dry path. Input gain, local distortion output and global output gain help you gain stage as you work.
The interface shows a colour-coded crossover display over an output spectrum analyser, with input and output peak meters and a gain-reduction meter per band. It scales from 75% to 200%.
There are 128 Factory Impact presets in eight categories with 16 presets each, including Drums Bus, Guitar, Vocals, Mix Bus and Creative Destroy. Saving and loading your own presets is part of the full version.
Drive, blend and dynamics parameters can be automated from your DAW.
