Long time since i've used these threads but since i'm in the market for new gear I know this is the best place to go. Anyway, I was quite a younger person when i got together my first bass rig, and now that i'm starting to realize i need to setup a better one, I decided to sell it off, add some money to what i get, and invest in a louder rig. Only problem is, I've been having problems with it that might be able to prevent me from fetching a better price. I currently use a three year old AmpegPF350 through an 8 ohm Yorkville 4x10. I joined a band and the shows we've been playing are forcing me to really crank it on the head in order to be heard, and after about 2 minutes the fault light would permanently turn on and the rig will just stop making noise, except for an occasional crackle or thump. I'd have to let the head rest for a few minutes before going at it again, where the problem would just repeat I'm assuming this has all to do with the class D's overload protection, and i shouldn't be worried about the quality of the head. I'd test it out if I could but I've left my cab back at my drummer's place 3 hours away. Anyway, if all is fine I'll probably get around $350 together for a new head, and hopefully i can run into some more money for a new cab. Any recommendations for something in that price range. or might it be more important to switch to a cabinet with 4 ohms? Sorry for all the questions, any help is appreciated though!
