Hi TBers,
I stumbled across a thread a while ago talking about replacement tubes for a Mesa M Pules 600, more specifically, tubes that will tighten up the low end a little bit..
I can't seem to find the thread anywhere, does anyone know which tubes I can throw in the head, to make the low end a little tighter, and slightly less pillowy?
Cheers
