Sometimes you go vintage – two controls, one true fuzz tone – with something like the JAM Pedals Fuzz Phrase Si. Throwing it back to some of the earliest, most dirt-simple and barebones fuzz pedals, the Fuzz Phrase Si blazes ahead for a real plug-and-play-style fuzz experience just like Mom used to make.

Two deeply interactive controls shape the sound of JAM's Fuzz Phrase Si. Onboard, Level and Gain controls closely interact to produce a heated fuzz tone with searing sustain and buckets of charming sonic character on tap. BC107 silicon transistors propel this ship full steam ahead with a surprising amount of versatility and capacity to clean up nicely along the way.

The Fuzz Phrase Si offers additional control via its internal trimmer that shapes its transistor bias. Open this guy up, find a baseline setting that butters your biscuit, and get off to the races. The Fuzz Phrase Si plays with all the character that makes vintage fuzzes so coveted without all the variability in performance and the "Is it breaking? Is it breaking? I can hear it breaking," that pervades older circuits. True bypass footswitching and standard nine-volt power operation with a battery connection make the Fuzz Phrase Si ready to rock.

Sometimes two dials are all you need. Believe it or not – there was a time we had to play our fuzzes uphill both ways in the snow. Luckily that's no longer the case with pedals like the JAM Fuzz Phrase Si.
