Having heard the rough mix, I can say 3 things
1) the song is incredibly tight - no wonder they sound like one guitar, I think that some people might not realise that there are 2 players!
2) unless you know the style of Ben (TO) and Jimmy, there is no way you can tell them apart
3) TO's tone is darker than usual, which I think contributes some of the similarity.
As Tim mentioned, when the gain is up and the dynamics are down, some tone goes out of the door. They are tracking a very hot signal and they do play the same phrases in many places. It shows how playing a song out helps when you come to track it in the studio. Everything is locked in place, the drums and bass are right in the pocket too. I suspect that in the final mix there might be a little more difference in the guitar tones, but that would be processing after the fact.
As a lower gain player, I like to let the guitar come through a bit more, and I am sure if they were playing at a lower gain setting there would be much more difference. Having said that, I am still amazed at the similarity between the sounds given the difference in equipment and style. However it is not going to make me sell any guitars or stop buying any more pickups!!!
Just waiting for my PG set - that will show TO tone :orcass:
