Did Paul McCartney ever use a small portable amp?

The Pignose Legendary 7-100 is the portable amp listed among McCartney’s gear. It’s a useful reminder that an artist’s kit can include modest little amps as well as bigger stage equipment.

The available gear entry doesn’t say when or where he used it, so it wouldn’t be safe to tie it to a particular recording or performance. The McCartney gear article provides the broader overview; if you’re looking for an amp yourself, the used guitar amps list is a relevant starting point.
