Positive Grid Spark Edge 4-Channel 65W Modeling Combo
Positive Grid · amplifier
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.
