Alright first of all im brand new to here to please bear with me ive been playing for only a year about 8 months, and just yesterday i finally got my first bass stack. its almost 7 feet tall (ya.....seriously..) -Peavey mark IV series bass head -Laney 4x10's -Laney 2x15's now this stack was used, not quite sure how old it is, the head has a little copywrite symbol and 1982 so im guessing that would be the year it was made. I got it from a rather small music shop called House Of Guitars. for only $600 bucks. so far, and i say this probably inaccurate because of my lack of expeierence. it has great tone.. awsome low end.. and its incredably loud... i turn the 2 post gain knobs to 5 and you can hear it down the street! (thats with the pre gains at about 2-3) now my reason for posting is i would really like to know what im dealing with or at least some type of input on this monster. from what i can tell heres the flaws ive found about it.. -the second speaker in the 2x10 is pushed in.. dont think its fixable without having to take it apart. -the back board of the 2x15 rattles...even tho the screws cant possibly go in any further.. me and my brother are planning on unscrewing the entire back board and putting stryophoam to get rid of the rattling. -the crossover knob just flat out doesnt do anything on the head. well i think that about covers it. Suggestions, Comments, or anything would be greatly appreciated. Thanks.
