Hi quality preamp to convert the high-impedance output to something with low impedance:

Audio frequency spectrum analyzer software (SignalScope for mac, i'm sure things exist for linux.)
Edit - it sounds like you want to detect these vibrations to quickly shut down the machining process? If you can characterize the criteria you are searching for and they are straightforward enough (i.e., power exists in a certain frequency band), an all-analog solution using bandpass filters, etc may give you the lowest latency. But you will have to be very precise in forming your requirements. For example, if your 'happy case' has -60dB of power at 300 hz with a 30 hz bandwidth, and your "stop now!" case is -55dB of power at the same frequency and bandwidth, AND you need to stop within 10 microseconds of detecting the condition....it's not gonna happen. There is not enough time to build statistical confidence about the change in signal power.
But if the changes are bigger and the time longer, you might be OK with analog or digital solutions.
Unfortunatly I cant, I dont know specific models / equipment here (I focus on electric and bass) and certainly dont know ones that will work with rocksmith.

Better ones typically sit under the bridge (requeres setting up your bridge again):

Careful with the one above, it has a small jack, probably can
​
Those are the very basic / cheap ones. I am dubious whether they would work as passive ones are pretty quiet.
​
Generally speaking, electro acoustics have a little pre-amp box to boost the level and take a 9V square battery so something like this (you can see that one comes with a mic and peizo:

But.. they require mounting into the guitar which you probably dont want to do.
​
I also found this one which is a little smaller:

Perhaps that could be just left to dangle inside the acoustic or with some thick double sided tape secured somewhere.

Yeah sorry, cant really be of much more help / not really my area of expertiese.
