these specific words...i know what there meaning!
but other i dont...if you have a site that explain all the concept for guitar and bass..it well be very helpful!

You might visit the Wikipedia page on guitars (http://en.wikipedia.org/wiki/Guitar).

or the one on basses...

I'm currently working on a bass glossary for my site that will answer many of your questions........but unfortunately it's still in the works with many other projects I have going on.

I find that many young(and old) players still have questions on what certian things mean. I will do my best to answer these questions in the simplest most understanable way possible.

Wikipeda is a very good source to answer your questions as well.

Good luck on your quest. :)
