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 Positive Grid Spark MINI Steve Vai Edition is a signature version of the 10-watt battery-powered portable Spark, produced in collaboration with Steve Vai. Signature editions of this kind typically pair distinct cosmetics with curated preset tones drawn from the artist's sounds rather than altering the hardware. The underlying amplifier is the Spark MINI: app-integrated modelling with backing-track generation and chord recognition, battery powered and portable. Independent coverage separating this edition from the standard Spark MINI is limited, so specific differences should be confirmed with the seller.
The Yamaha THR30IIA Wireless is a 30-watt 2x3.5-inch wireless digital modelling combo built for acoustic guitar, part of the THR line that pairs Yamaha's VCM modelling technology with app control and Bluetooth connectivity. The A designation marks the acoustic-voiced model within the THR range, distinct from the electric-guitar-focused THR combos, and it includes acoustic-specific effects such as feedback suppression alongside reverb and chorus. Wireless connectivity allows guitar and app control without cables. It suits acoustic players wanting modelled amplification with practice and recording features built in.
