Buying Bass Guitars
A bass guitar is pretty similar to a normal electric guitar, except the typical version only has four strings and it has a larger body plus a slightly longer neck. If you are planning on learning to play the bass, then firstly you should educate yourself about the instrument's 'role' in a band, and secondly you might want to understand the varying techniques used which change depending upon the type of music genre that the particular song belongs to.
Bass playing has some interesting techniques associated with it that also have unusual names. For example, 'slapping' is achieved by (usually) striking the E string (normally the 'bottom' string - IE - the 'widest' one that plays the lowest notes but appears to be the 'uppermost' string when the guitar is strapped on and the strings are viewed) with the thumb towards the neck of the instrument. The thumb is then pulled away quickly. If you listen to any 'funk' music, you will hear this technique being employed quite a lot.
Another of the bass techniques is called popping. This is done by slipping one of the fingers right underneath the string and then pulling it outwards and releasing it so that it pops back. Both of these techniques (slapping and popping) can be used effectively by alternating between one and the other. Obviously, this can be done a lot more quickly than repeatedly doing the one technique with either just the thumb or just the finger.
The bass guitar is used very closely in combination with the drums to create the 'backbone' of a band - they provide the rhythm, or the melodic 'bottom' of a melody and the harmonic foundation for other members of the band who are playing chords. Therefore it is important for the bass player to have good timing. There are a disproportionate number of men who play the bass because due to the thickness of the strings, it needs a certain amount of strength and finger toughness to play for long periods of time without causing injury (particularly if the music genre involves an aggressive, rapid style.)
Also many larger built men find that their finger tip size, hand size and limb length make it much more comfortable and productive for them to choose the bass rather than the electric guitar. Specifically, a rhythm guitarist will quite often only play chords, which require hand dexterity and ideally, thin fingers. So for someone with big 'sausage' fingers, who also might be a little more 'clumsy' than others, the bass is the best solution as they may find normal guitar playing quite frustrating.
Bass guitars can be played using the index and middle finger in alternate 'plucks'. The thumb is often rested on the top of the pick-up nearest the middle in order to support these two fingers while playing. But the bass can also be played with a pick (or plectrum). There is also a pick that is made specifically for the bass which is larger than a typical guitar pick.
If you are looking to buy a bass guitar on the internet, some good tips are to check that the sender will be using adequate packaging to protect the item in transit. Also, you should view pictures of the guitar closely if it is second-hand in order to try and find any marks or other giveaway signs that the instrument has been mis-treated or dropped, as any damage could affect the quality of the sound produced by it.
As with any online purchase, particularly if it isn't cheap, one should take great care to examine the credentials of the seller (if it's on eBay) or website. Look into their selling history, check their refund policy and look for any other information that will help you to make a safe and satisfying purchase.
