Hey guys, I am relatively new to tube amps. anyway, I have had my fender pro junior for about a year and a half now. I just play it with the tone knob all the way down pretty much all the time. I think it is time to get some new tubes, also to change the sound a bit. I am really wanting a little bit deeper sound with some earlier breakup if possible. What tubes do you guys recommend to get these characteristics, or what tubes do you prefer (reliability, qualities, price...etc) Thanks in advance
