Since around 1998, a wah is the only pedal I've ever used.
I've got reverb/delay rackmounted, but chorus, flange, boost, compression,... all gone.
But, I have to hear the way.
One of the early songs with great subtle wah work that hooked me was this oone:

I was for tour of the album after Bridge Of Sighs. I think that was For Earth Below.
Awfully good. Jimmy Dewar was a GREAT singer, just as good live as on record.
Robin was the first of the Hendrix disciples that took that approach to the next level.

All Along the Watchtower is also on this album.
