Cut the strings allowing for about 4 inches past the machine head.
Slot the looped end into the right slot on the bridge and hold it taught while inserting the other end into the hole in the tuner, then wrap it around counter clockwise and make sure it doesn't slip. Repeat for all strings.
Wood doesn't affect tone. Grow up.

Its not too difficult.its pretty much the same as restringing a guitar but you cut the excess before wrapping round the post rather than after.i restrung a bass for the first time this year.i was a bit nervous but did a decent job.
