Thanks! I'm glad you liked it and that the track sounds like an anime OP to you (or to your friend).
As for the guitar, I used the Kontakt VST Shreddage 3 Hydra library, and took from that Hydra Infinite Lead (Smooth) guitar, slightly tuned. But if you mean bass guitar, then I used Shreddage X Master Multi, along with ReValverMkIIIdotV.
