    Well you could try using an LM301 and a an LM386 in
    conjunction.  The 301 you can hook up to boost say 1-1000 in
    gain and the 386 you can set up for 20.  This will give you
    a range of 20 - 20000 in gain.  That good enough? :)  Now if
    you are talking micro volt levels it's a whole new ball game.
