That chrome finish looks very professional. The text is reprinted in red and looks spot on. He even got the PSA and wheeliebin stickers reattached. I'm impressed.
Didn't Boss make a 'one off' Shiny DS-1 after they sold lots of units (like 6 million or something)? Although it did have slogans emblazoned all over it. I think the 'only one ever made' statement gives it away as a fake, there's probably only one because it isnt cost effective to reprint and chrome it.
It looks kind of cool, but the chrome finish reminds me of the Scott Ian signature pedal that Digitech has out...Joe Satriani should get it if he still plays those chrome finish Ibanez's he played on the Flying In A Blue Dream-era...
