Vertigo offers three types of tremolo: standard amplitude modulation, “harmonic” tremolo that bounces between high and low frequencies for an effect between tremolo and phaser, and a dirtier “Bias” tremolo.

The stompbox includes depth, speed, output and LFO waveform controls, the latter allows for morphing from a Fender-type opto tremolo to sine, square and reverse sawtooth waveforms.

Thanks to the free Neuro software editor (available for download), you can extend the shaping capacities of Vertigo with additional EQ, delay and filter effects (flanger) which modulation speed can be synced to the tempo.

Here’s a demo of Vertigo, followed by a presentation of the Neuro/One capacities with MXR pedals:
