Dunlop MXR SUB Machine vs Pigtronix Octava

The Dunlop MXR SUB Machine and the Pigtronix Octava are both pedals sharing octave, full. The Dunlop MXR SUB Machine leans fuzzy. The Pigtronix Octava leans transparent and shimmer.

Similarity
citedBlended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement. Shown only within a gear class, and only where there's enough evidence to be meaningful.

Description

The MXR Sub Machine is a two-channel fuzz and sub-octave pedal from MXR by Jim Dunlop, combining an upper-gain fuzz channel with a sub-octave generator that drops the guitar signal one octave below pitch. The pedal features independent controls for fuzz and sub-octave level alongside a dry signal blend, allowing players to mix the three signal elements in any proportion. The Sub Machine produces dense, synth-like fuzz tones with the sub-octave adding a deep, full-frequency foundation below the fuzz. It is suited to players who want the textural complexity of a fuzz and a sub-bass element in a single enclosure without separate octave and fuzz pedals.

The Pigtronix Octava is an all-analog octave fuzz and frequency doubler featuring an onboard low-pass Filter control that lets players achieve singing octave-up tones anywhere on the neck without needing to adjust their guitar's tone control. Controls include Volume, Blend (mixing in the octave-up effect), Filter (low-pass cutoff for the octave circuit), Drive (adding warm J-FET preamp overdrive), and Fuzz (activating the fuzz circuit), letting players layer clean octave-up shimmer through to devastating, full-wave-rectified shoegaze fuzz distortion from one pedal.
