I just bought a MIJ sd1. The pedal has no #'s, no back plate, the only thing that says Japan is the PSA jack.it is not the smaller looking one,but it has a PSA decal.The board looks "too New" Did they use some MIJ parts on MIT pedals I have only 2 days to send it back.How can I tell. Did some MIJ pedals look like this one Any help would be of help thanks
