Thanks for the responses. I'm hoping to get back to gigging at some point. I have always used a brighter sound which led to the GK's. I like the sound of my Backline 600 with the 4 strings but lacks a bit with the 5. It does however make a killer keyboard amp. I'm leaning toward the Fusion setup. Those Neo cabinets look like they have a large tone range. Plus they utilize the full power of the head.
80's Charvel/Jackson 3, 90's Jackson Futura ex, and this decade a Jackson Dave Ellefson CBXV 5-String. GK Backline 600 and 410 cab. Fusion 550 Neo 112, Neo 212.
