The layout is from the Guild Brian May Box schematic, which is marked as designed by Pete Cornish, but he has disputed this at one stage.
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, 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 ringmaster 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
ReplyDeletePity 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.
