"Set of 6 380017a modules. We designed our 380017a voice modules (voice chips, VCF/VCA, filter ICs) in-house, and we carefully test every single one for the Roland JUNO-106, HS-60, MKS-30, MKS-7, GR-700. Our modules are socketed so that you can easily swap them out in the very unlikely event of failure. We're confident that our modules will last—So confident, that we offer a lifetime replacement warranty."
