I'm new here and hope I can contribute as well as learn, Any how I have a question,

I was looking at the 6 band eq design on "General Guitar Gadgets" website http://www.generalguitargadgets.com/index.php?option=com_content&task=view&id=46&Itemid=26 and wanted to use it as a pre amp on my 100w amp build instead of the standard pre-amp. It is powerd and has a gain control so I think it will work, but what do you experinced builders think?
Thanks,
J
