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 ZVEX Double Rock Vexter was originally designed at the request of J Mascis of Dinosaur Jr., who wanted two Box of Rock circuits combined in one enclosure with independent stomp switches. Each of its two channels can be configured as either a Distortron circuit or a Super Hard-On boost circuit, letting players build combinations like two cascaded Distortrons, two cascaded Super Hard-Ons, a Box of Rock paired with a boost, or a Super Hard-On feeding into a Box of Rock. Adjustable sub-frequency controls carry over from the Distortron circuit, giving low-end shaping alongside the flexible channel routing. In effect, it condenses elements of three separate ZVEX pedals into a single, highly configurable dual-stage unit.
