i like them. I like the way they sound. I like it when they do solos, especially when the solo sounds different to the rest of the song. I like it when the first 3 notes of the solo are good, and then maybe the next 10-1000, but definitely the last 3. Especially if the last 3 notes make up the song's melody. I like it when the soloist doesn't really play a solo much, but just sort of mashes the frets. I like it when the solo lasts the entire song. I like it when the solo is fast, i like it when it is slow (as long as it is the right kind of slow). I also like guitar playing which isn't soloing, like chords and shit.
Similiarly, 2 guitars are pretty good. I like it when they are in the left and right channels, especially when they both solo over each other. I also like it when one is soloing, and the other isn't quite soloing, but isn't quite playing the song either. I sometimes like it when neither are soloing.
I also like acoustic guitars
