thanks for the info.. will this vibration cause any distortion when i plug it into the amp tho or is it just cosmestic?
: : I just bought a bass, its a fender p-bass mexican. When not plugged into an amp and i pluck the strings the A string tends to vibrate against something but im not completely sure... like a rattling type noise even... any idea what this might be? will it effect the noise it makes through the amp? also i have a regular guitar amp from my electric guitar and i was wondering if i can plug my bass into this or if i have to get a new amp.. thanks...
: Ahh yes...I forgot...an amp. The problem with using a guitar amp as a bass amp is that the spekers tend to tear themselves apart, not being tailored to the low frequency output of a bass. They can be used, and I have heard them used qutie succesfully, but it only tends to work with higher end systems with a separate head and cab. Another problem you will run into is that the bass sound is carried by wattage, and guitar amps usually are much lower wattage than bass amps. Bass amps also utilize tuned speaker enclosures. This gives a small cab the ability to produce large amounts of bass. Guitar cabs tend to be tuned to higher frequencies than bass cabs if they are tuned at all, and open backed cabs are not uncommon. This type of cab will really sound poor for bass, although it rocks with a guitar. I would have to suggest getting a bass specific amp, even if it is just a small practice amp. I started on a Gorrila GB-30, and it did just fine for initial learning. That's my two cents.
: The sound you are hearing is the string bouncing against the frets as it vibrates. This can be caused by a couple of things...One: As Jcor said, improper action. This is the height of the strings above the neck, and if set too low, it can make the string buzz when plucked.(too high of an action makes the bass harder to play) Two: a high spot in a fret. this is less common, but does occur, especially in lower end basses. This is a when a certain fret is too high, not allowing the string free range to vibrate, and causing a buzz. Three: Improper neck bow...this is when the struss rod is adjusted incorrectly, causingt he neck to have a bow or hump in it. this also can cause that problem, though is less likely, as it is only the A. Any of these problems can be fixed by a reasonably competent tech, and are pretty cheap fixes. Keep it real.
