JAM Pedals replaces Germanium Fuzz Phrase with BC107-loaded Fuzz Phrase Si
March 29, 2024 · 3 sources
JAM Pedals has replaced its Germanium Fuzz Phrase, formerly loaded with CV7003 variants equivalent to OC44, after stocks ran out, with the BC107-loaded Fuzz Phrase Si1. The fuzz pedal is the newest addition to the maker's standard line, coming a year after the last Fuzz Phrase Ltd pedals sold out2.
The Fuzz Phrase Si uses silicon BC107C metal-can transistors, described by Guitar Pedal X as searing and zingy1. The Fuzz Face-style circuit has 14 components versus the classic 11, with Level and Gain controls1. Silicon avoids the temperature sensitivity of germanium, though there is no external Bias control1. The maker lists Level as adjusting output volume "while also allowing for versatile tonal shaping," Gain as setting the amount of gain, and an internal trimmer as setting transistor bias, factory-set at 4.5V3.
"After meticulous testing of various silicon transistors, the BC107s emerged as the unequivocal choice. We proceeded to fine tune the circuit to these transistors, securing all the attributes synonymous with the Fuzz Phrase legacy."
The pedal is true bypass, runs on a 9V battery or 9V DC adaptor (tip-negative), draws 3 mA, measures 7.5 x 12 x 5.6 cm (2.9 x 4.7 x 2.2 inches) including jacks and pots, and weighs 250 g (0.55 lbs)3.
