The Stomp Under Foot Rhinosaur is a handmade bass fuzz pedal, a fuzz design built specifically for bass players. Premier Guitar's reviewer described it as one of a generation of pedals in which "bass-specific fuzz pedals are plentiful", and created by Matt Pasquerella, who "wanted to do something different".1
Circuit and design
The Rhinosaur circuit is inspired by the Colorsound Bass Fuzz, a pedal known for maintaining low end and packing a punch. Like the original, the pedal employs BC549C transistors.1
The Colorsound Bass Fuzz design lives on elsewhere too: General Guitar Gadgets sells a DIY project kit and PCB that is a replica of the ColorSound Bass Fuzz, describing it as "similar in design to the ColorSound Jumbo ToneBender, but tuned more to bass tones".2 Colorsound also made fuzz pedals in other formats, such as the Fuzz Phazer, where a switch underneath the rocker turns the fuzz on and off.3
The Colorsound name carries history with bass players: Joe Perry recalled that in the early Aerosmith days, circa the early 1970s, he was using an orange Colorsound fuzz pedal.4
Controls
The pedal has a simple control layout: a trio of knobs for level, tone, and fuzz.1
| Control | What it does |
|---|---|
| Level | Sets output level |
| Tone | Shapes the tone |
| Fuzz | Sets the fuzz amount |
Premier Guitar's reviewer gave an example of how the controls behave together: "I rolled back the level, tone, and fuzz to around 9 o'clock for low-gain distortion suitable for rock/indie music."1
Build and size
The Rhinosaur resides in a compact 2.5" x 5" box. The pedal feels rugged, is adorned with slick graphics, and is handmade.1
What reviewers said
Premier Guitar's review listed the pedal's pros as: "Powerful fuzz. Strong lows. Sturdy construction. Simple controls. Compact size."1
