As of SingStar update version 5.0, at least in EU and AUS, the availability of playing a guitar is there, even without purchasing SingStar Guitar. You will, however, need to purchase guitar compatible tracks, or guitar upgrades for songs already owned.
The second of Sony’s SingStar spin-offs, following the very nearly successful SingStar Dance, SingStar Guitar apes another popular physical action game genre, that of the recently downtrodden band simulation game. Taking the form of a Guitar Hero-esque Rhythm Action game for its new additions, SingStar Guitar is also playable as a karaoke game just as with any other SingStar release, and yet does not suffer from the increased price-tag one would expect.
SingStar Guitar's intro video gives you an idea of how Sony intends it to be played. The camera arcs around a pair of blue and red virtual fretboards as the instantly recognisable chiming riff from The Cult's She Sells Sanctuary kicks in. As we swoop past floating notes and giant volume dials a short, soundless video clip appears, showing a slightly nerdy-looking chap playing his Generic Third-Party Guitar Controller (TM) while a woman – his girlfriend, perhaps – cosies up to him, crooning into her wireless SingStar microphone. They're your archetypal SingStar couple, and the perfect audience for this guitar-based spin-off.

"The SingStar franchise has become the victim of its own fame, ever since arriving on the PS3 and introducing the SingStore sales of the retail discs have become an afterthought to the consumer, who now having to buy just one disc gets access to well over 1000 tracks to download, plus you don’t get forced to have a few ropey numbers that always get skipped."
