Different Types Of Transistors

[xtjdx]

I'm getting to the stage where I want to start experimenting with different types of circuits for distortion pedals. I've done a 386-based circuit that gave a synth-like grind which I will be putting into pedal form very soon, and a 741-based circuit that I didn't enjoy very much but got to work (which at this point is really the only thing that matters, right?!). Now I want to venture into transistor distortion but the stock at Radio Shack is pretty limited. I'm only spending about $.50 per transistor, so not much damage done if they're unuseable, but what are some transistors readily available at RS to use in a distortion circuit? Will pretty much any NPN silicon transistor do the trick in one way or another? I'm still not sure exactly what role transistors play in amplifying a signal (but that's the whole point in experimenting!) or what the differences between them are. I picked up 3 types of them, so either you guys can help me out and/or I'll find out once I get home and build the circuit! Apologies if this has been answered before, kindly direct me if that's the case. Thanks in advance for any help offered!

I'll bet your neighbors are glad you're not into high explosives! Unlike opamps, which are optimized for simple cookbook-style circuits with a few outboard components, transistors are a little more difficult to use, but you'll figure that out right quick.

My recommendations would be the 2N2222 NPN (RS#276-1617) and the 2N3906 PNP (276-1604) in the 15-paks. They're both general purpose, and at about eighteen cents each, you can afford to destroy quite a few of 'em.

I picked up the 15-pack of 2N2222s yesterday, so I'll be working with those tonight. I usually don't dive right in to something without researching first, but since this is so inexpensive, might as well. I'll be reading up in my huge book today about them, so hopefully that will save a few.
