I have seen Optics picks on ebay and volume/wah pedals in some people's rig pics and have never heard the history behind them. I take it they were a dunlop creation though?
They had nothing to do with Tom Scholz or SR&D (except in name only). I want to say that they were made by Dunlop for the Japanese market. I would think that if it were made for the US market by Dunlop, they'd still be making them (and they aren't).
My opinion - these pedals aren't worth anything. Well, I guess they are no better or worse than any other wah/volume pedals. I remember back in the day, people couldn't give them away.
Collectable? Well, a collectable is only worth what someone else is willing to pay for it.
I disagree, they're a good wah, just different from the usual overly coloured wah.
They're very clean sounding, so good for your acoustic 12-string etc when you want clean filtering.
The Hall Effect pot also means it never gets scratchy
I had one in the 90's and regretted getting rid of it so I just picked up another (for cheap)
My CAE wah is okay, but very coloured with those fasels, more suitable for distorted rock tones
Of course I wouldn't pay the silly $400 prices for a Rockman wah, but for $110AU ($70US), it was worth grabbing!
