What kind of guitar pedals or processors do I need to get this kinda tone?
That's all that's on it.
Actually, after comments, there is a single delay repeat on it too - so quiet I didn't spot it to start with.
The rest is just a very simple clean Strat sound, front pickup.
It doesn't hurt at all that he plays it well.
I was trying to find some earlier refs for a historically similar sound, but basically it's a brighter, modern version of a classic strat sound.
Hendrix is similar, but slightly dirtier - YouTube keep taking down the good mixes of this, so this is the best I could find [he's playing the wrong guitar in the video, it's definitely a strat on the record]
..and I must at least bow in the direction of probably the originator of the sound. From over 60 years ago, the late Buddy Holly…
If you want to hear the record at its best, then seek out the version from the Cornerstones album, which was remastered beautifully in the late 90s.
