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.59% — moderately similar

Positive Grid built its reputation primarily on digital modeling technology, most visibly through the Spark line of smart practice amps that use software-driven amp and effects modeling rather than traditional analog tube or solid-state circuitry, and the Reactor 100 sits within that broader digital amplification approach. The 100 designation suggests a higher-output model within the lineup, aimed at players who want Positive Grid's modeling and connectivity features at a volume level suitable for small gigs or rehearsal rather than bedroom practice alone. Specific amp modeling library size, control layout, and connectivity features for this exact model aren't confirmed from available sources.
The Positive Grid Spark EDGE is a four-channel 65-watt digital modelling combo, considerably more powerful than the practice-focused Spark and Spark MINI and built for rehearsal and small-venue use rather than desktop practice. It retains the app integration that defines the range while adding the channel count and output needed to work with other musicians. That places it between the practice amps at the small end of the line and the Spark LIVE at the top. It suits players who want modelled tones with enough power and channel flexibility for band use.
