Not sure if Katy owned a Telecaster or if it was rented/borrowed, but this picture (taken around 2008, during the One Of The Boys era) shows her with a Fender Telecaster As for the amp, it is some sort of Vox amp. At first I thought it was a Vox AC30 amp, but someone told me that it might be a Vox Pathfinder amp. I also know that in the Part Of Me documentary, they show her with a white Fender Telecaster. Might be a prop tho but I know that her guitarists used a bunch of Telecaster type guitars. What year is this Telecaster. Looks to be a newer Telecaster but it might also be a CBS Telecaster. Let me know. Teenage Dream was a good album, but it did get overplayed ad nauseam and was a hard album to follow up. Then 1989 and Born This Way came out and Teenage Dream was compared to those 2 albums. At least she and Taylor Swift are friends now and have reconciled.
