NGramFilterFactory would then take that one toke ("electric guitar")

AFAIK it only produces prefix-strings like
gui
guit
guita
guitar
etc.
So that you can do a prefix search without a wildcard. So it is enough
to search for "guit" and you do not need to search for "guit*". The
latter wildcard string can make trouble with stopwordfiltering and (at
least in solr 1.3) with text snippet generating.
