Hey, what's up? I run my Marshall on the crunch channel with my cool cat OD always on (love the tone). My question is, does this eat up my tubes quicker? And, if so, will it eat up power tubes or preamp tubes (or both?).
probably not, its not the big a deal
Your preamp tubes, perhaps a little - but they can last years anyway. I can't see it causing any significant wear on your power tubes.
Alright, cool. Feel free to close this thread mods. Thanks for the help!
