this cable serves to connect two Roland GK2 or GK3 compatible products, for example a Spuler Paradis guitar or a Godin Multiac SA or a Polybass equipped guitar with a Roland guitar synth or a StringPort or a Spicetone 6appeal.
the connectors are smarter in that:
unfortunately the Roland GK-3 pickup is very tight and does no receive the connector as it is. a knife can solve the problem. I hope we find a better solution for this soon!
