stretching new bass strings

[Newton Hunt]

Once you have the string installed you can grab it around
the middle of the string and give a good pull, about an inch
out or so.  Retune and do it again.  Those strings are
likely running around 50% breaking tension so it is safe to
do this.  You don't want to pull it as hard as you can or it
might break on you if you use your full body weight.  Leave
it a little sharp then come back in a day or so to retune.
