I've borrowed this pedal to test before and I am pretty sure it had a black label. Unfortunately I pulled the velcro this time and the label seems to be gone.
I opened it up and the sticker with the serial is there, but curiously it has only 5 digits when I expected to see 6 numbers. See pics. Serial is 50900. i tried to see if any digit was faded or cut, but doesn't seem to be the case. It does say Japan though. I looked it up, but found no info on this. Any experts? Could it be that the leading 0 was ommited, making it 050900? Would that make it 1981?
More tidbits, I also remember it had a mod sticker from a local tech indicating a mod which is now also gone, I think it was the power supply from ACA to PSA, the PSA mod sticker is still there.
Regarding flexibility and sound I loved the Waza, so not sure if it was the best decision, but I always wanted one of these old ones just because I'm a bit of a collector, so I figured I could just go and buy another Waza later on if I wanted to.
