hi myles I've read your article 'bout tubes but I'd like to ask you some specific advice.I own a marshall jtm 612 I've got svet el34 as power tubes.I got a 12at7 as ph.inv. and It works great. Now I just want to find the right tubes for pos v1 and v2 : I want the best performance in clean-going-distorted situations , lots of sustain , clarity and "fullness" - a nice blues-rock tone.I mostly use the boost channel to get my best tone , expecially at reasonable (doesn't mean very low, just not eazr splitting) volumes. A thing that I really hate about stock tubes is that they get nasal and a bit "boxy-and-dark-sounding" when pushed hard with a stompbox.I play a strat, mostly in the neck position.
