ok, i am bringin in a bass for a trade for a cab, the dude on the phone said, sure we can trade ya in, no problem just bring your bass in. ok, i bring my bass in and the guy wants to set it up and try to lower the action a little. crank crank crank crank. needles to say, i watched him crank away the life of my neck right before my eyes. "i almost got it set." crank crank, other sales person says, "dude, thats ebough." they take my bass to the backa nd about 30 minutes later the guy comes back. "sorry, cant give you anything for it. we saw a bass a few weeks ago that was just like this and had a lot of issues so we dont want to take the risk with yours." i guess they dont realize that some basses just come off of the assembly line as crap. i tell him that ive had the bass for years and i have had no problems with it at all. he says, "well, we have to play it by a case by case basis and your bass is screwed (he said this in different words, but meant the same thing)." i say, "whatever." he gives me a free shirt and i leave. i get the bass home, pop open the case. hit the open A...buzzzzzzzzzzzzzzzzzzzzzz. i am getting buzzing on all of my open notes. i call the dude and ask him what they did to my bass. "we, uh, uh, we, um, we put tightened the, uh, trussrod all the way, um hoping to lower, the uh, action a little bit." i tell him that you really shouldnt turn the trussrod on any bass more than a half of a turn per day and whatnot and he tells me, "dude, all he did was tighten it, its not gonna hurt your bass bud." it pisses me off that he called me bud for one, but it makes me mad that he questioned my knowlege of setting up my bass. so, im pissed and i dont know what to do. he told me to just turn the truss rod a half turn counter clockwise and it would be fine and they would fix it if i couldnt get it. the last thing i am going to do is take it back to guitar center. i am sorry about this long story, but i need to vent. what should i do? i guess im gonna go do what he told me to do and let him deal with it if it gets screwed up. NEVER trust your beautiful instruments to the unknowlegeable staff at guitar center. any insight on the situation would be much appreciated. thanks.
