Now in an MXR mini housing, the classic 108 fuzz gives you all the same vintage fuzz tones in a much smaller footprint. Like its larger predecessor, it's loaded with the silicon bc-108 transistor for a round and dirty crunch. This classic 108 fuzz also has the same no-nonsense control interface-just crank the volume and fuzz controls to your liking and start riffing. Use the buffer switch on the side to make the fuzz play nice with wah pedals.
