hi all
a bud of mine owns a marshall valvestate 65w combo (one of the old valvestates, not the AVT series). now, the problem is, in order to be heard over our drummer he needs to crank it up to 7 or so, and it feedbacks HARD. even at volume 4 or so its still squealing like a pig. he doesnt crank the gain, doesnt have too much presence and treble dialed in, stands about 15ft away from his amp etc..
furthermore, it sounds like ****. at first i thought its because i'm used to tube tone, but it isnt. in fact, my old POS peavey SS amp sounds WAY better. i figured that it may be because of the preamp tube those thingys have (the amp is 10 years old and the tube was never replaced), because a broken tube would indeed cause such extensive squealing and shitty tone (especially after he told me that the amp sounded great a few years ago). i told him to replace it.
but now he went into GC and wanted to buy a new tube, but they told him that based on his description of the sound his amp is broken and it cant be repaired (they havent seen and/or heard the amp). so i'm kind of thinking those guys at GC just want to sell him a new amp and make some money, but i'm not sure. so guys, please tell me if i'm right and it is indeed the preamp tube, or if it is really impossible to repair the amp.......but really, i doubt that.
