It may seem odd but im a huge Katy Perry fan, nad ive been trying to figure the bass since god knows when, and when i stumbled across a guitar tab practically giving me the bass last night, i knew i had to make a tab.

Come in with Electric Guitar.(I have no idea what the first 2 bass notes are which are played whilst Katy sings "Oh Oh", It'll be something obvious undoubtedly, so comment what it is if you know.)

Pre Chorus

A|6~-4~-2~-4~  That last 4 isnt meant to be there, i just find it sound better, down to preference
E|-----------  so that 2 needs to be half the length it should be to fit in that 4, if you prefer it with out the 4, hold the 2 for TWICE the length as the 6 and the 1st 4.
