Listening to some Loverboy.
Tonewise, neck pickup, hard knee compressor, scoop the high mids, decent amp through a 1x15" cab with a horn.
Play with a pick.
Scott was using a Spector bass which I thing has a P pickup. I don't hear anything special about its sound but use round wound strings, a bit of tube amp distortion, a compressor and play with a pick (or hit hard with your fingers).
Saw them the first time at Montreal Forum on May 8th 1982 (the day that Gilles Villeneuve died) with Bryan Adams opening the show with its first album.
