Thank you very much for the informative reply !!! I love the head so I will not get rid of it. So that means off to the shop she goes do you have any idea about how much this will cost me to fix ?? (New tubes and all) also what brand of tubes do you think I should get ? From what I hear tubes made in Russia are the best but I really do not know. (There are Groove Tubes in there now). I have a PRS guitar and a Fender American Standard that I put Lace Sensors in. The style of music I play is in the mode of bands like Failure,Sunny Day Real Estate,HUM and a touch of Rush. Do different brands of tubes really sound different than others ?? Again thanks for your reply !!
