Ive had this amp for about 6months now, at first i was very pleased with it, got some decent distortion and was fond of the on-board effects. But now im starting to notice that its losing its power, sounding muddy. Does anyone else have similar experience or could give me advice...?

I was warned off buying a valve amp, but i ignored it, now im starting to think twice. Are there any better amps, of similar price and or wattage?

Thanks

I think the best thing to do is to turn up the volume knob of you guitar, if that does nothing try turing up the amp's volume, or gain on it. But thats my 2 cents.

You did buy it new right? I assume you did. Try going back to the dealer where you purchased the amp and ask them, it may be a fault within the amp itself. I used a Marshall Valvestate 8100 Head for the better part of 2 years and had no problem with it at all, I did also get the amp used, very well used. It could just be something lose inside that was caused during the manufacturing process.
I have never heard of any amp like that just start losing power, I know tube amps do but I havent heard of valve amps doing so.
You could also send an email to Marshall and inquire about that from one of the marshall reps, they reply quite quick I have found, they are very helpful.
I dio hope you get that fixed, as for other amps about the same, check out some Peavey products, for an inexpensive head that isnt all that bad of quality, take a look at them.
