I just used a variable resistor and adjusted it so there was very little clipping. There are some volume contorls that let you set the level. If I were bulding
one to used full time I would use clamping diodes for protection. I watched 
a fellow blow the front end out of a ditital scope using a Pizo sensor with
no amphlication. I saved the files as raw data files and wrote my own dsp
software.
