Firstly, unpack your gift, that you have received prior to your birthday, and put it down on your bed. Mine was an original Fender Super Bass 7250s, manufactured in Mexico.
Then, take out the strings and sort it according to the size. Please be careful not to be confused by the numbers, you can figure the strings name from their thickness.
Emily = E thickest
Bobby = B 2nd thickest
Goofy = G 2nd thinnest
Donald Duck = D thinnest
Next, take out your bass from the gig bag and put it on your friend's bed (in my case, Asai's bed).
Then, take off the old strings, one by one (of course, haha).
The picture below is to differ the Fender stock strings with the original Super Bass 7250s. Firstly, from the appearance, the 7250s have a gold-plated ball, while the stock string have a nickel-plated ball. The covering threads for the 7250s is black, while the original one is red.
Next, when all your strings are removed, take this opportunity to clean up your fretboard. It's not everyday you removed your strings. So take a static-free cloth, and clean up the fretboard. Don't use any bleacher, hair wax or facial foam to clean the fretboard as it will make you looks stupid. Oh, and it will also ruin your fretboard.
p/s: wish me luck for my final. All sarcastic expressions and harsh words are adapted from a punk called ilyas, ilias, alias, whatever that a.h was called. He should F.O.D.
till next time, ROCK ON!
