This Austone Vibrostomp is one of the bigger pedals out there, with a footprint of 4 inches by 4 inches. The pedal contains both TREMOLO and VIBRATO. For my March show I pulled off two pedals from my board, a tremolo and a chorus pedal, and replaced the two of them with an Austone Vibrostomp.
A toggle switch selects between the tremolo and vibrato modes. Another switch selects a HIGH or LOW range in the LFO (high and low speeds). The LED glows with the rate of the modulation - COOL!
The inside of the enclosure was signed by Jon Bessent. RIP. Austone products are no longer in production.
