Nembrini Audio just released their free Big Stuff Harmonic Distortion-Sustain plugin, modeled on the classic Electro Harmonix Big Muff pedal, an incredibly popular fuzz pedal beloved by indie rockers to metalheads. Now, this classic fuzzy tone can just as well be applied to synths and organs as well, of course.

The plugin is available as VST3, VST3, AAX and AU and for Mac, Windows and iOS.

Here’s SuperCrunch – a free guitar amp VST plugin by Linda Audio. It doesn’t aim at replicating any specific real hardware but instead just goes for the natural sound of a classic tube amplifier, ranging from sparkling clean to gentle crunch and wild rock/metal distortion.

There’s control for input/output gain, drive and brightness and two channels (crunch and lead), cabinet simulation, gate as well as the possibility to blend in your guitar’s clean signal and a 8 band equalizer to help dial in your wanted tone.

SuperCrunch is only available as VST/VST3 for Windows, no Mac or Linux versions and is completely free, unless you decide to donate a few bucks to help support the development of plugins like these.
