Firstly I have a "MB TTE500" and a "GB Shuttle 9.0"
The TTE has that geat mid "valvey" sound and the top end is nicely controlled using the "colour" control, an LPF by any other name, but whilst the bottom end is hugely powerfull and thick, I find it a little bit muddy. (Mainly B-string stuff)
This is a hard one to explain, but whilst I like the TTE a great deal, I still prefer the ultimate bottom end sound of the Shuttle 9, it's much clearer, and has more depth of the low frequency reproduction. (bass control at mid), like it's got a lower frequency response?
A TTE/Valve amp that has the ability to reproduce the low B-String frequencies with the depth and definition of the Shuttle would be a nice one to own. Maybe, its a "you cant have it both ways mate" thing? I've tried the "GB Streamliner" BTW, did not like it, "muddy as hell" maybe its a cab/head pairing thing?
Just thinking and looking for idea's here, It's no problem keeping both, but maybe I'm missing something? The cabs I'm using are a pair of Vanderkley 112's
