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.

The ENO EX-Inferno is a high-gain distortion pedal from the Chinese budget effects manufacturer ENO Music, delivering extreme gain distortion for heavy rock and metal applications. The Inferno name suggests a high-gain, aggressive distortion character suited for heavy playing styles. Controls include Gain, Tone, and Level for basic distortion shaping at a budget price.
The ISP Technologies Empyrean is Michael Sweet's signature distortion, built around ISP's noise-reduction expertise: the pedal integrates their Decimator gating so that very high gain stays usable without a separate gate in the chain. Voiced for the tight, saturated modern-metal rhythm sound Sweet uses in Stryper, with the low end kept controlled rather than loose.
