His red Gibson is obviously the same one he played in the 60s. He still gets the same trademark sound (like on The Story in Your Eyes, my favorite). Justin said himself on his site "It's the 335 through a Marshall Fuzzbox, mains powered [the only I've ever seen] into a Vox AC 30."
What does he mean by "335". And I wonder which model Marshall Fuzzbox. I know the Vox AC 30 amp is rare but they are making new ones.

I don't have the answer to your question, but I did find these guitar sound links very interesting.
