So, I see your time spent in the reverse of how you are looking at it. I think you learned a lot of subtle little things or had things you are starting to realize reinforced.

Guitar player looking for a bass player, I like older rock. I can play knocking on heaven’s door, smoke on…….. Would like to learn song name, ……….

If you put out an add with wording kind of like what I have above, when you get a call back, the person already knows what kind of music you like and what songs to learn quick before they show up to jam. Who knows someone may call who wants to learn a song you know in trade for teaching you a song on your list.
