To some degree, different glues will go into different joints, but most modern mass-produced instruments are largely built with aliphatic resin-based glues (e.g., Elmers and yellow wood glues). Martin was rather conservative in the date they converted, but even they use such stuff now. The last generation of instruments were largely assembled with hide glue. Many small shops, especially those to specialize in historic reproductions like lutes, still use hide glue. Hide glue is very solid and not prone to creep over time like the aliphatic resins, but may be a little more susceptible to weakening at high temperature.
