The Universe was the 7 String one, famously used by Korn in their early incarnation. 😉 The JEM is the Steve Vai one, although iirc the Universe was designed by him too, but the JEM is more famous for being so. Nice find anyway. I love Westtexasred's LP too. 😎
Btw, I'm pretty sure the "Jnr" thing means it's a cheaper version, I remember seeing a cheap JEM once and wondering why it wasn't ridiculously priced like the rest I'd seen.
