I know these have been compared a lot --- Oh my...It's happening again....GAS..... Digging my TH500 for the most part...REALLy love a tube grind to my sound. I still feel that when I dial that in, in my TH500, it compresses too much....only tried a STL 600 ( I think it was) quietly in a music store....really dug it so far though.. Question Streamliner users: Can I get a more "open" grind/overdrive w/ the Streamliner series? I'll swap it if y'all think it can! Some folks are just never satisfied! ha!
