If you're using a 1.5.1 or later version of git-svn, you can do so pretty easily by editing your .git/config:

If you already have something like:

[svn-remote "svn"]
	# url here is the repository root, and 'mpc/trunk' in fetch
	# is the relative path within the repository
        url = https://svn.musicpd.org
        fetch = mpc/trunk:refs/remotes/git-svn

You can just add the following lines to the config in the above section:

        branches = mpc/branches/*:refs/remotes/*
        tags = mpc/tags/*:refs/remotes/tags/*

If you have something like:

[svn-remote "svn"]
	# url here is the full path of what you're tracking,
        url = https://svn.musicpd.org/mpc/trunk
        fetch = :refs/remotes/git-svn

Change it to something like in the first example (assuming you have read permissions to the repository root).

If recompiling SVN is feasible for you and the branches (as a fresh checkout) are as big as trunk, I highly recommend the do_switch patch for SVN which lets you transfer only a delta between the branch/tag point of trunk:
