Andrew Guyton is the luthier that Brian May has employed in recent years to make replicas of his Red Special guitar, and also to do some repair work. He has recently been asked to restore the guitar, which was last done by Greg Fryer in 1997 so it’s had nearly 20 years of use since then.
Mr. Guyton has posted a short video about this on his website, showing the pre-restoration condition of the guitar, and he promises to publish a longer video of the restoration work in September. I shall be very interested in watching that! In the meantime, here’s the link to the relevant page on his website.
