What it is
Audio Vari-Speed Tremolo is an AAX Native, AU, and VST3 effect plugin from Antelope Audio built to recreate the sound of a vintage guitar amplifier's tremolo circuit. It pairs a five-position wave selector with a Vari-Speed rate control that lets the modulation frequency drift in real time, giving the pulse a looser, more hand-played feel than a standard fixed-rate tremolo. It's available both as a native plugin and as a Synergy Core real-time DSP version for Antelope hardware.
Who it's for
Guitarists and mix engineers chasing classic amp-style amplitude modulation, whether that's warbly vintage rock tones or subtler rhythmic movement on a modern mix. It also works well on clean guitars, keys, or synth pads where a subtle rhythmic pulse adds motion without changing the underlying tone.
