What should i do with these Transistors?

Hello everyone this is my first post so go easy on me.

I have some transistors i was given by a friend they are labeled as follows:

BC303-5
BC301-6
BC179

Are any of these any use in a single transistor fuzz and would it be a simple enough project for my first build?

Cheers people :)

At least when I build something, the most expensive parts are usually the jacks/switches/pots/caps for pots.  The actual bits that do all the work like op-amps and transistors and resistors and capacitors are nothing in comparison.
I made the transistor angry.

"At least when I build something, the most expensive parts are usually the jacks/switches/pots/caps for pots", i can cover the cost of them man was just wondering if these components are useful that's all not that i want to sound like an idiot  :)

never built before and like the idea of recycling stuff so..........

DIY Stompboxes Beginner Project?
LPB-1?
Electra distortion?

There are tons of projects out there. Don't know much about your transistors, but if you have a breadboard and a multimeter you can build and tune any of the common circuits to suit them.

If you know what the transistors are (PNP or NPN), silicon or germanium, gains of the actual transistors you have (not the "gain range" from a datasheet), and leakage, then people could offer you more ideas. Most of this info *should* be available by doing Google searches (except, of course, the gain and leakage -- you need to measure that yourself).

BC179

Numbers referring to no other info...
  Get other info, data sheet tells some...
   Better yet a really inexpensive DMM with 'Hfe Checker' [doesn't measure leakage of GE's] can provide a gain reading and pinout. The reason there are 4 holes: CBEC each [one side PNP, the other NPN] is so transistors of various pinouts can fit easily in 3 of the 4 holes and line up to give a good ballpark gain reading [when this happens, write down the pinout which = gain measured].
  Whether that is 'good' for 'fuzz' are other indefinable matters: If they're bipolar transistors with relatively low leakage then they'll work in...appropriate circuits [probably most fuzzes or boosts].
Convention creates following, following creates convention.

If I were you I'd find a simple OD, boost, or fuzz schematic. build up the circuit in a breadboard and plug those transistors in and see what happens.  Try all three of them in single transistor circuits, or mix and match them in multiple transistor circuits.  Experimenting is the best part of building in my opinion...good luck
