i want a 2nd cable for 2 player on rocksmith - do i need another real tone cable or will any USB guitar ;lead work as i have seen them on ebay for less that £10 ?

 

not rocksmith but does anyone have any knoledge of Blackstar Core Id amps and the insider software ?

 

cannot get the software to recognise the amp and their forum is long dead

Yes, you'll need a second Real Tone cable for multiplayer.

As for the amp, you might as well consider replacing it as that's not too good of an amp.

I bought a second Real Tone cable at a pawn shop for $10. They usually throw the software in with the games and the cable in the glass display case with the guitar cables and stuff.
