Michael Schenker

In the first question he mentions the pick he uses is a Dunlop .60mm

"Interviewer: Do you have a type of pick that you can't live without?

Schenker: I play Dunlop 60mm. I guess it was a type of pick that was lying around and I got used to it."

Looks like a nylon pick here: https://www.vintageguitar.com/wp-content/uploads/MICHAEL_SCHENKER.jpg

Michael used Dunlop .88 mm picks and also D'Angelico strings with standard .009 gauges

"SOUND"

"For more than a half century, Schenker’s signature instrument has been a Flying V. The relationship began when he borrowed brother Rudolf’s red ’71 Gibson Medallion V with T-Top pickups and plugged into a Marshall stack. Early photos depict a stripped mahogany V, later painted black, then white, and finally the trademark graphic black and white panels. He also played a Les Paul Standard and white ES-1275 in the studio. Gibson issued a tribute model V in ’85 and Dean currently markets his signature version. He used .009 Fender Rock and Roll strings, preferred high action, a glass slide, and Herco gray nylon picks held with thumb and two fingers."

"Schenker plugged into 50-watt 1987 Marshall heads (Presence, Treble, Middle and Bass on 10, Volume at 8), later graduated to 2204 and 2205 models, and often chained two together. In ’73, he routinely used at least two full 4×12 stacks. A departure from the norm, he experimented with a Pignose amp on much of Lights Out. His effects were minimal – a modified Crybaby wah pedal and WEM Copicat tape echo."
