The Positive Grid Spark Control gives you direct access to useful functions of your Positive Grid Spark Amp. The footswitch with four switches is compatible with both Positive Grid Spark Amps and the associated app and is particularly easy to set up. In addition to the four factory pre-installed button assignments, up to four additional scenarios with different button assignments can be programmed. The footswitch works completely wirelessly and has an integrated rechargeable battery that can be used for up to 4 months on a single charge.
