RE: Mt 57..... Runs like crap
I used 800 wet/dry with a good flat plate glass and honed my reed block down very evenly.
Since you have it off, I hope you will too. Mine was pretty much flat, except where the screws went through to hold the reed on.
Agreed the chip is probably not too much of an issue. I could not get the photos to open up. It just said Loading.
Personally, I'd be hesitant to run it with a damaged reed, but Tomy is a good guy, he will get dialed in.
