    Apr 02 2011 · Germanium tends to be a bit softer and warmer than Silicon but Silicon tends to maintain attack and be less "mushy". Germanium also tends to be lower in gain than Silicon and most Germanium transistors are less stable. Germanium is usually used for more vintage type stuff and Silicon for a more modern type sound basically (if that helps).
