Are these of any use in a circuit for stomp?

I found a few of these lying around the workplace and I was wondering if they could be adapted for a circuit:

Burr-Brown INA103KP
16-pin DIP

I am not EE enough to crunch the facts and spit out a use for these so I figured I would consult the pros  ;D

Suggestions??

EDIT: Excuse my manners. For your consideration:

You can build a nice mic preamp with them, I don't know what else they'd be useful for, they might distort in an interesting way if you drove the crap out of them for that overloading the mixing desk sound. Minimum supply voltage is +-9 volts (18 volts) so that limits interest as far as stompboxes go.

I don't understand this. Don't "most" of our stomps run in the vicinity of +9-12VDC?

Depends on your point of view ::) ::) ::)

Exactly, we mostly use +9 volts, this needs at least +-9 volts which means a positive supply of +9, and a negative supply of -9 or 18 volts overall, I suppose that doesn't mean it won't work on less but that's the minimum they recommend.

ICL7660S +- 12V, Max1044 +- 10V... and a couple of caps, doesn't seem like much effort for more headroom. I started using them so I could play with Anderton effects more easily, even stuck one in the breakout box for my breadboard.
I could understand builders baulking when it was just the Max and it cost 4 quid, but that ICL is under a pound now.
