The Suhr Rufus Fuzz was designed to sound like a fuzz and tube amp in one, giving you tones from classic '60s rock to aggressive grunge-era fuzz. The Rufus has a 3-band EQ for total versatility in tonal shaping and can actually be used not only with your guitar but with your bass as well. Switch between Normal and Fat modes seamlessly with the Rufus' Multi-Function Technology footswitch, which can also save your last mode choice so you don't have to sweat remembering your favorite modes and sounds.
