No, there is not a second generation of the SRC6. That beautiful beast has been put to "sleep". The new "SRC6MS" is a six-string bass, with Low-B, E A D G C tuning. More like a short-scale six-string bass, but the old SRC6 is like a guitar tuning, EADGBE, an octave lower. I upgraded mine with Bartolini bass bars with series-single-parallel swit and preamp, and strung it with the now discontinued La Bella Hellcat flatwounds. I like mine very much and this SRC6MS is not an upgrade as much as a different instrument. I'd rather have the high E than a low B. But having both would be fun.
