I (misguidely) answered a question about HiFi equipment used to listen to music with a reply about instruments used in songs. This question
I think that equipment questions are on topic.
For instance, in 'name of song' what intrument created this perculiar sound 5.43 mins into the song ?
I'd draw a line at 'what specific make/model/year [instrument] did [musician] use on [track name]' as this is far too specific and probably should be in the musical performance site...
So, are questions about instruments used by artists on recordings or live permitted?
