How do you play this guitar tab?

Question

ok well i know how to play tabs but not this 12^13^15 i don't know how to play this i mean the little up sign i want to know what it means and how to play this

Answer 1

"^" more than likely means 'bend'.  Bend the 12 til it hit the pitch of the 13 then again until the pitch of 15.

Answer 2

It looks like bends to me. If you have the actual sheet music it should be obvious on there.

Answer 3

most tabs use h for 3h5 a hammer on.  that looks like a bend for most standard online tabs but you should know the song and listen.  that may help.  since, you know, bends sounds wildly different than hammer ons.  

Answer 4

It's a hammer-on.
