How to unlock the Beneficial Friends achievement in Rocksmith - Definitive Guide
All you need to do is plug in both cables, tune your guitar for both players by switching cables. As soon as you pick a song it unlocks, you do not even need to play the song.
This is a very easy trophy, however, this will require a second cable. You can earn this with just one guitar. The Xbox and PS3 USB Tone Cable are identical so if you have a cross platform buddy, invite him/her over. This can be done solo.
You don't have to play a song. If you only have one guitar, plug in two Tone Cables into your PS3 and plug one of them into your guitar. Now, just start a multiplayer game, select a song and finish the sound check with your guitar and then unplug the one cable from your guitar and plug the second cable into the same guitar and finish the sound check . The trophy will pop when the game checks your tuning.
Go to the Multiplayer, play with a song with someone, and it’ll unlock.Unfortunately there is no online multiplayer, so this must be done locally.
We connect it to the console and click the tip with our finger.
