I need to replace my tubes for my fender DeVille 4 10 . I would like a more edger, harder sound like muse,van halen, alter bridge. I love the cleans I have now but I also what a blues tone too like SRV,hendrix,Zeppelin. I was thinking kt 66's but I know that they could hurt my transformer due the 1.3 (A) instead of my currant 6L6GC's .9 (A). So what tubes should I go with or what tubes would the guys and gals of UG suggest. Then what is the deal with the brands any particular brands better than the other?
You aren't going to get edgey or hard with a Deville. You can directly replace 6l6s with KT66s but you need to rebias the amp.
