Based on the classic fOXX Tone Machine of the '70s, the Marsling Octafuzzdrive from Interstellar Audio Machines is a octave fuzz pedal with a distinctive sound derived from the use of a phase splitter and rectifier for octave overtones. Sporting a thick fuzz, smooth tone, and pronounced octave effect, the Marsling Octafuzzdrive is a surprisingly versatile pedal.
The Marsling Octafuzzdrive features two vital improvements over its '70s inspiration—the octave up switch is now on a on/off footswitch instead of a toggle switch, and the pedal now features a tone control switch, which selects between two different capacitors, providing three unique tonal profiles. Furthermore, the tone control has been improved by increasing the treble-side ton capacitor to make it easier to get good tone from the treble end of the tone control, addressing a major complaint of the original Tone Machine. This all-analog pedal provides top-mounted I/O jacks, making it easier to fit into your crowded pedalboard. This pedal can be powered by either a 9V battery or a 9 VDC power supply (both sold separately). The Marsling Octafuzzdrive is made in the USA.
The Tone Machine has a lot in common with the Fender Blender, but with a more pronounced octave and smoother tone as well as the ability to disable the octave by turning off half of the phase splitter. And the tone is not unlike the Superfuzz, although it uses a different method of octave generation to get there.
