i have a vince ray limited edition smokey amp... just the same as they put in cigarette boxes but a lot prettier (although having not smoked much in the past few weeks fag packs do have their own charm)... sounds fairly harsh on its own - plug it into my 2x12 and its reallly a lot nicer than it should be for £30. i am just always amazed at the sound i can get from one 9 volt battery
so if you have a cab i would go for a smokey
edit... and they work fairly well in front of an amp as well so would push the TT into extra gain
