With the Positive Grid Spark LINK, annoying cable clutter and loose contacts are a thing of the past. The compact system is not only particularly space-saving, but also easy to use: Simply plug the transmitter and receiver unit into the corresponding connections on the guitar and on the amp or Pedalboard , switch it on and get started! The system can be used for up to 6 hours at a time and allows a transmission distance of up to 21 meters, so it can easily be used in the rehearsal room or on smaller stages. If several band members use the Spark LINK or interference occurs, four different channels are available to ensure clear signal separation.
