Blackmore's effects (delay?) in Son of Alerik and Hungry Daze (Deep Purple)

[Baby_Boom]

Hi,
can you tell me about effects and techniques used in certain parts of two Deep Purple's songs off Perfect Strangers album? Did Ritchie use a delay pedal or these are studio effects added during the production stage?

1 Hungry Daze 2:37 until 3:02 mark. See and hear below (I can hear a delay effect thorough, although Blackmore is known to not use delay at all?).



2 Son of Alerik:
7:07 - 7:57 (I am not sure if this is all delay or he picks all those notes but for example the part at 7:22 - 7:23 must be delay. Then from 7:40 he does some volume swells?).

 

Any answer appreciated.
