Pretty solid vibrato.
Good vibrato makes such a big difference in a player. I’ve listened to guys that are considered lords of shred and then you hear their vibrato and it’s sterile, you feel nothing. Then you hear someone like Jimmy Page or SRV and when you hear their vibrato, you think to yourself, “good lord, but that’s insane vibrato!!!”
Sayce has good vibrato. Sends him to the next level. Bravo mr. sayce, well done. You took the time to learn and unleash powerful vibrato, plus, it also has to be inside you somewhere and you need to figure out how to access it.
You know when you first started playing and you would be laying in bed, fantasizing about your future rock n roll glory? and in your head you would be playing a magnificent song? You would imagine this super cool riff but no way you could hope to figure out how to play what you are hearing in your head, well, I think epic vibrato is similar, it has to be in there somewhere and not everyone can call upon such magnificence. Sayce can.
