But from my memory, which is mostly washed away by gin and vermouth, some, if not all, Hams are avid electronic tinkerers. The web is filled with little preamp circuits you can build with three transistors and a 9v battery, and can put in an Altoids tin. Wouldn't this be a better solution than fooling with software. How many of them to you need, after all? Here's a list of some you might look at: http://www.till.com/articles/GuitarPreamp/ http://www.passdiy.com/ http://www.record-producer.com/learn.cfm?a=3062 ($5 mic preamp, which the article claims competes favorably with a $1500 preamp. I have no idea if it is smoke or mirrors or both.) http://www.record-producer.com/learn.cfm?a=3080 (Related to the previous) I got these by searching for "preamp" on digg. P.S. After I wrote this reply I actually looked at the other replies, so this is not completely relevant. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
