I am looking for a simple amplifer program.
I have looked at audacity, but I would have to be 'recording' to get 'playthrough'. There is supposedly a .vst plugin, but I have not found it yet.
This is for my wife to be able to have a simple amp (using my little Asus Eee900) for when she is playing her guitar and needs a bit of a boost.
To echo the microphone jack through your speakers, you can run this on the command line:
pactl load-module module-loopback latency_msec=1
When you're done, disable it with:
pactl unload-module $(pactl list short | grep latency_msec=1 | awk '{print $1}')
For electric guitars, there's also Guitarix (available in the repos) which simulates a tube amp and provides distortion and other effects.
I never got pulse loopback running without latency, though haven't tried it for a while. This is an old version of the jack setup I use for passthrough:

- it's worth noting that if you're using the same audio device for microphone and output then there may well be a mixer control that enables pass through in hardware which has the lowest latency you can achieve.
The advantage of using a Jack setup is you can run an amplifier simulator like Rakarrack or Guitarix and play into a an audio workstation like Guitarix. I normally use an amp with a USB output (lots of recent modelling amps have this: Fender Mustang, Yamaha THR, Blackstar ID:Core), you can also use one with a line level or headphone output, or a an instrument impedance box. I have used a guitar straight into a laptop microphone input and it can be made to work. http://epenguin.imalone.co.uk/2011/11/let-right-noise-in.html
As others have said, involving a computer can be a bit risky playing live, but for home and studio use it does expand the possibilities, like re-amping in software http://epenguin.imalone.co.uk/2011/12/re-amping-with-guitarix-and-ardour.htm...
