I hope this is okay to post here. I stumbled upon a post that helped me figure out how to use a bandfuse guitar cable with Rocksmith on OSx Mac. Without any problems like latency or noise. No hack files needed at all. 1 Plug in your bandfuse cable 2 Go to your applications folder, utilities, and run Audio MIDI Setup 3 Click the little + in the lower left to create a new Aggregate Device 4 In the Aggregate Device select the BANDFUSE USB Guitar ADAPTER, I used the default volume level .375 and dB 5.939 4 Rename the aggregate device to "Rocksmith USB Guitar Adapter" 5 Right click the Rocksmith adapter, and select "Use this device for sound input" 5 Restart steam 6 Start Rocksmith 7 go and calibrate and tune your guitar I tried a CM108 guitar USB interface I orderd from amazon first and had tons of noise and crackling. When I switched to the Bandfuse cable all my problems went away!
