The MXR Classic 108 Fuzz fits the whole Fuzz Face circuit into a mini enclosure, and it sounds exactly as big as the name implies. It’s built around the BC108 silicon transistor, the same component that put the crunch in ’60s and ’70s fuzz tones, and MXR have kept the circuit faithful while adding one genuinely useful modern touch: a side-mounted buffer switch that makes it play nicely with wah pedals and buffer-heavy rigs.
If you’ve ever wanted a no-frills, one-job fuzz that does the classic thing without taking up half your board, this is a strong candidate.
The panel is minimal by design. Reading left to right: Output on the left, Fuzz on the right. That’s the whole interface on top, plus the buffer toggle on the side and a bypass footswitch at the bottom.
Output sets your overall level. Fuzz controls the gain, ranging from a relatively mild, amp-like grind at the low end up to a full, saturated wall of sound at the top. In the demo above I’ve set up a Fuzz sweep so you can hear the gain range from 0 to 10 against a fixed Output of 10, which makes it easy to pick out your preferred setting before you ever touch the hardware.
The BC108 silicon circuit is brighter and more aggressive than its germanium cousin. The All Out preset (Output and Fuzz both at 10, buffer on) shows the pedal at full tilt: a round, dirty crunch with plenty of sustain and a forward midrange. Back the Fuzz knob down and the dirt opens up into something grittier and more responsive. The silicon character means there’s more edge and less warmth compared to germanium designs, but it also means the tone stays consistent regardless of temperature.
The buffer switch is not just a nice-to-have. Running a Fuzz Face-style circuit after a buffered pedal or wah normally kills the pickup interaction the circuit depends on. Flip the buffer on and the pedal becomes chain-order agnostic, which is a real quality-of-life upgrade for players who don’t want to restructure their whole board.
The Benson Amps Germanium Fuzz is the most direct contrast worth making. Both pedals are Fuzz Face derivatives, but they land in very different places. The Benson uses germanium transistors with active temperature regulation, which keeps it stable in ways an unregulated germanium pedal never would be. It also adds an impedance knob and pickup simulator so you can dial in rolled-back-volume tones from anywhere in the chain. The result is described as more overdrive-like than fuzz-like even at full settings, staying articulate and dynamic throughout its range.
The Classic 108 goes the other direction. Silicon is harder, brighter and more forward. There’s no impedance control, no temperature stabilization, just the raw Fuzz Face topology with a buffer switch for chain placement. If you want a pedal that blurs the line between overdrive and fuzz, the Benson is the one. If you want something that commits fully to the vintage silicon fuzz character, the MXR delivers it in a much smaller box with a much simpler formula.
There’s also a side by side page for this one: MXR Classic 108 Fuzz vs MXR Timmy Overdrive, both pedals on the same loop so you can switch between them mid-phrase.
Classic rock, blues and psych players who want a straightforward, recognizable fuzz voice without the upkeep concerns of vintage germanium. The mini footprint makes it easy to slot onto a packed board, and the buffer switch removes the usual wiring headaches that come with Fuzz Face designs. The honest caveat: this is a two-knob, one-character pedal. If you need a fuzz that cleans up gracefully into overdrive territory or has a sweepable tone control, look at something with more range. For the player who just wants the classic silicon fuzz sound, switched on and loud, the Classic 108 delivers without fuss.
