Can I use a ps2 guitar her controller on ps3?

May be...

Yes. You have to buy an adaptor. Look on ebay or amazon for ps2 to ps3 adapter or a lot of the times, ps2 to usb adaptor usually shows ps3.

yes you can because Sony made them both the ps2 and 3 so it will def work unless it is broken but if not your good to go

if you had a ps2 and got a 360 it would def def def no work Microsoft and sony

hate each other

opposites

No. The ps3 only excepts USB interfaces. The PS2 guitar connector is proprietary only to the PS2.

yeah you can .

yes with the adapter
