A few days Ago My brother Steve told me that sooner or later i should get something called a capo and some polish for my guitar . I have to ask what are these things .

Also I know I am years off from upgradeing to a a real nice guitar but I have to say I've heard the electric and still like acoustic more but was have often heard the term semi acoustic which I don't know much about .

I'm just asking these questions to get a basic understanding and also to expand my guitar knowledge for the future
