Positive Grid Spark 40W Modeling Practice Amp
Positive Grid · amplifier
The Positive Grid Spark is a 40-watt digital modelling practice amplifier built around app integration rather than front-panel controls alone. Its selling point is software: the companion app offers amp and effect models, and features that listen to what you play — generating backing tracks in a chosen key and style, and transcribing chords from songs so the amp can accompany practice. That makes it a practice tool as much as an amplifier, aimed at players learning material rather than at stage use. It suits home players and learners who want modelled tones plus practice functionality in one desktop-sized box.
