OK, just transplanted the Crawlers from my ESP Eclipse (mahogany body / maple cap, mahogany set-neck, rosewood fret board) to my Fender Showmaster (Basswood body with Fender floating trem, maple set-neck, rosewood fret board) and what a difference! I used to scoff at people that said that wood types, etc, changed the tone (I used to think it was 99% to do with the pickups) but the Crawlers in this guitar just make me realise what a poor match they were with the Eclipse. Where as in the Eclipse they were as smooth as Lionel Richie in a velvet jacket, in the Showmaster they absolutely roar - and they are definitely staying put in there (as long as I can come to terms with having zebra pickups in an all black guitar!). So in answer to my own question as to whether Crawlers sound OK in a basswood guitar guitar? Yes, they do.
