Blended 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.44% — somewhat different

The Crazy Tube Circuits Motherload is a high-gain distortion pedal from the Greek boutique manufacturer, providing heavy, full-frequency distortion with the premium component quality and refined circuit design of the CTC boutique approach. Delivers the thick, sustained saturation needed for heavy rock and metal applications in a boutique format that prioritizes harmonic richness and note definition within the high gain. Made in Greece by Crazy Tube Circuits.
The ZVEX Box of Rock is a distortion pedal built to simulate the everything-on-ten sound of a non-master-volume Marshall JTM45, the amp behind a great deal of classic hard rock. Its distortion engine runs from a whispered crackle at low drive up to a punchy, raucous crunch, with Volume, Tone and Drive controls; the voice sits at the lower, more amp-like end of the distortion spectrum rather than in modern high-gain territory, and can turn bass-heavy and slightly flabby at maximum gain. A separate footswitchable boost channel provides an extremely high-headroom, low-hiss unity-to-50x gain stage closely related to ZVEX's SHO, refined to sound more like a hot amp input and less glassy. The boost follows the distortion in the chain, so engaging both hits the amp harder for leads. This is the Vexter series version -- the same circuit in ZVEX's more affordable screen-printed factory finish rather than the hand-painted line.
