AMPFILTH – ANALOG NOISE GENERATOR (VST3)

Digital rigs are clean. Sometimes a little too clean.

Real amps hum. They hiss. They buzz quietly in the background while you hold your guitar and think about the next note.

AmpFilth brings that back.

AmpFilth is a lightweight VST3 plugin that adds controllable analog-style noise to your signal chain, recreating the subtle imperfections of real amplifiers and electrical environments — without coloring or altering your guitar tone.

Your guitar signal passes through completely untouched. AmpFilth simply layers the noise floor that real gear naturally has.

The result? Your digital rig suddenly feels a little more alive.

CONTROLS

Hum

Simulates power-line hum and harmonic buzz, like a real amp sitting on a stage with questionable grounding.

Hiss

Adds high-frequency analog-style noise similar to vintage amps, tape, and older analog gear.

Tone

Adjusts the brightness of the hiss so you can dial in anything from subtle background noise to vintage-style analog fizz.

Output

Controls the overall level of the noise layer.

WHY WOULD YOU WANT THIS?

Modern digital guitar rigs are incredibly quiet. In some situations, they can feel almost unnaturally sterile.

AmpFilth adds just enough electrical grime to recreate the background feel of a real amplifier sitting in the room.

Use it subtly to add realism to recordings, or crank it up if you want full-on noisy amp chaos.
