The layout is for the Guild Brian May Box, which on the Guild schematic is marked as designed by Pete Cornish, but he has disputed this.
There's a massive write-up here on Fryer Guitars, including photos of inside Brian May's Pete Cornish built pedal board, and inside a pretty vintage looking Pete Cornish treble boost, which also happens to contain a buffer. Given that Fryer rebuilt AC30's for Brian May and has a few of his own treble boosters, I think the man knows a thing or two.
Either way it's a buffered treble boost. You can either wire this up as buffered or true bypass, whatever you prefer.

Not much to see here.
And one difference to other treble boosters from the Rangemaster family is the 10n input cap vs the standard 4.7n.

How does this treble booster isn't affected by the input buffer, treble boosters and fuzzes don't really like buffers before them
Pity Mr Cornish isn't here to answer in person. ;-) It will sound a little different due to the impedance differences, but that doesn't mean that it will sound bad. This is also a silicon booster vs germanium.
