Alexander Pedals · pedal
The Alexander Pedals Riff Instant Tone Sanitizer is a limited-edition discrete Class-A preamp and boost pedal released in 2020, with Alexander donating ten dollars from each sale to the Inter-Faith Food Shuttle charity. Its three controls are labeled Kills, Most, and Germs, corresponding to output level, high-frequency content, and voicing character. The voicing control sweeps from a darker and more mellow tone at low settings to a fatter and more saturated sound at high settings. Requires a standard 9V center-negative power supply.
