I’m not much of a wah guy…but I own two.
I had an idea for an original composition that- as I heard it in my mind- absolutely required a wah. So I set about shopping for one. Ultimately, I settled on a T.Rex Gull wah, for a variety of reasons. Problem was, by the time I found the product, it was discontinued. I found 2 websites selling their final ones. I ordered one…but couldn’t tell if my order went through. I tried again, but it was gone. Their website had automatically updated their inventory, but I STILL couldn’t tell if I had been the purchaser or some else. So I ordered the one from the other website.
They both arrived on the same day.
Thing is, I’ve never even taken either of them out of the box!
So unfortunately, I can’t say if it’s parkable.
And the cherry on top: a short time after retirement of The Gull, T.Rex released the Shafter wah, which, AFAICT, is the identical pedal but in a more traditional appearing housing*.
All that said, one of my axe-slinging friends has a Fulltone Clyde that he loves, and one of his main methods for using it is in a parked position.
* just saw a comment on another thread in which someone at T.Rex said the Shafter is based on the Gull, but isn’t identical. Didn’t illuminate anything further.
