hello all,...just looking for some advice on what would be the best type of tubes to get for my Fender twin reverb (pretty sure it`s a `75).i tried to ask these guys at the music shop in the closest town,but they just wanted to sell me guitars,and just tried to sell me the most expensive ones,i guess so they could make more.
these are the tubes it has :
4-6L6 GC
3-7025
2-12AT7
1-12AX7A

now a friend suggested that i try out "groove tubes",he said they were alright.just figured i`d ask you all for your opinions before i made any purchases. Thanks.
