The JAM Pedals "Shards" Fuzz Phrase Si is a silicon fuzz pedal from JAM Pedals, a version of the company's Fuzz Phrase circuit built with silicon transistors. The maker describes the Si as "securing all the attributes synonymous with the Fuzz Phrase legacy."1
Controls and setup
The Fuzz Phrase Si keeps its front panel simple, with two knobs and one internal adjustment1:
| Control | What it does |
|---|---|
| Gain | Sets the amount of gain. |
| Level | Adjusts output volume, while also allowing for versatile tonal shaping. |
| Internal Trimmer | Sets transistor bias, factory-set at 4.5V. |
Power is straightforward: the pedal runs on a 9V battery or a 9V DC adaptor with a tip-negative plug, and draws 3 mA. That low draw means it will sit happily on almost any pedalboard supply. JAM Pedals specifies True Bypass switching, so the pedal is out of the chain entirely when off.1
The bias trimmer is an internal control, factory-set at 4.5V. If you open the pedal to adjust it, you are changing the operating point of the BC107 transistors and therefore the character of the fuzz.1
The Shards artwork and the Fuzz Phrase family
"Shards" is one of JAM Pedals' custom-artwork editions of the Fuzz Phrase Si. The maker states that "Every custom artwork pedal is a one-of-a-kind hand-painted piece," so the pedal you receive will differ in detail from the photos on the product page.1
