if you want to get into audio, a good long thin common screw-driver is tops for setting pot-switches on things like wireless mics, and for setting dip-switches on some gear (but much less common in the audio world) And if you want to continue on in the industry, the tools one carries are as important for credibility as ones resume, so owning a good quality multi-tool will be very good later on (or even if you just do community theater stuff outside of school) But for now, if its tools you are needing, get just those tools for now, and worry about multi-tools down the track. Cheaper, less hassle, no pain if you loose them.
If you do want to go with a multi though, I would go with the SOG, you may find you need to belt carry it, but at least you will have the tools you want, and can put the blades back later. With nearly anything else, you'll just have a tool you need to replace later. I just looked, and it seems like you can blade swap with the paratool and the pocket powerplier as well. so those are good options as well.
