Morley wah?

Anyone have any positive and/or negative experience with Morley wah pedals? Any type at all.

I have a clunky old ('76, I think) Morley WVO Wah-Volume. No other wah ever really worked for me. The size doesn't bother me, 'cuz I wear 13s and some pedals feel too small. Also, the optical circuit means no scratchiness.

I didn't like it because it felt like I could only go to the high end of the sweep and there was no real bass sweep and I personally like the scratch.
