: There is a very good single chip preamp by analog devices. Their part number is SSM2017. It's cost around $3 or $4. You'll also need a DPDT switch, (2) 9 volt batteries, 5K ohm pot, mic input jack and output jack and a piece of circuit board. All except the chip can be obtained from Radio Shack.
: The chip can be ordered from any real electronics store. Circuit info can be obtained here... http://products.analog.com/products/info.asp?product=SSM2017
: Page 6 is the circuit you want. Rg is the 5 KOhm pot. To get +9 and -9 volts fron the batteries, you will have to put them in series and center tap them.
: The alternative is to go to musiciansfFriend.com and order a mic preamp for approx. $100 .
You may also find http://www.paia.com/ interesting. They have a number of
DIY electronics kits for musicians.
: : Ok, someone below told me that my mic trouble was not because of the DAC in my sound card, but because it's not being preamped.
: : It was meantioned that I could MAKE a preamp for less than $15, but I don't even know exactly what a preamp actually is, let alone know how to make one!
: : Get someone give me the lowdown?
