This is a fresh release. If you are a recent FX fan, then the ADA name won't jog any memory of a glorious FX era- the '80s! Yes, it's that shredtastic time in guitar history when speed is it. ADA was there to propel tone the digital way but things are rack-mount & not that portable or bedroom friendly compared to the offerings of today. The GCS-2 you see above promises to be affordable & manifests some desirable tones in use with both valve & solidstate technology. As the label implies, it's a cabinet simulator, so if you think you have your pre-amp settings/ effects all set, the GCS-2 should complement your tones.
