Well, I prefer the delay at the end of the line, it is a matter of taste, just try and swap.

I beleive he is still using a DD3.

Most important, his pedals seem to be in serial (wich surprised me).

I personnaly put them in // and get better tone.

BF-2 setting is not that a big secret, you can guess it by hear, but depending of the era, settings are not that strict.

I remember there is a picture where you can see the dials, will try to find it.

But you will never get the same prince flanger sound, he tweaked something and I do not know what exactly

For the vibrato (very rare and expensive)

Bootleg "Open Session" track "I love you in me".

For the octaver + DD3

Bootleg "Stars and Bars" first track.

For DS-2

The whole undertaker album (I beleive).

etc.
