I like the JC Emerald, and while a number of bassists (as you've seen) really enjoy it, I personally consider it more of a guitar thing. It hasn't sold anywhere near as well as DW and it covers the same general gain territory so I've come really close to getting rid of it, but I still regularly get at least one order for it every month, and with Black Eye and Wrecking Ball gone there really isn't anything in my lineup that would woo our 6-string brethren into Sushiland. So I'll continue to keep it around for now.
I was thinking about modifying JC Emerald to get more low end out of it, but I'm worried that it would start to just be a slightly different DW. So the circuit remains as-is per the original Marshall schematic.
