I spent ages on this very quest.
I found that in my situation the ebs didn't really tick the box for me, I can't really define what it was ( helpful huh!), so I tried the pork loin, but I found that whilst playing on my own it sounded great, but wasn't quite the ticket when playing at volume with the rest of the band.
In the end I settled with the hardwire tube od for my low gain grittyness, and I'm currently trying the markbass bass tube marker for higher gain stuff
Hth
