Oh yes, that instrument is weird.
Yeah, I had to explain to some people that it's not a guitar. It's a synth-lead type of instrument, not unlike stuff like what you hear in... Motoi Sakuraba music (Tales games), or if you wanna get more CV-ish, the instrument heard in Cordova Town in Curse of Darkness or the Victorian Fear instrument in the 2nd part of the song, in the Arranged Portrait of Ruin track.
It's not an electric guitar. Can't stress that enough.
