does anyone know if these are good for any distortion pedals or anything? they seem pretty cheap so i was curious.

  High speed switching is what read there.
  You can probably build something with them, but the HF specification may or may not be what you want. 
Convention creates following, following creates convention.

According to this:

it looks like pretty low gain, as well as low voltage...

 Dunno about those germaniums, but I just scooped up a bunch of those 2n5133... might just be mojo, but I swear I hear a difference with these. Thanks for reminding me where to get 'em!

HF 5.5 IS pretty low
and $1 is not really very cheap

Those were the tranny of choice at E-H for a while.  Of course, at that time, the reasons for "choice" would likely be a combination of cost, serendipitous availability, and tone.  Some folks prefer the BMP that used a quartet of them.  My old Muff Fuzz used a pair, though I was none too thrilled with the tone.

Meanderthal

 Yeah, I used them in a hog's foot, Axis/Foxey lady, and a bmp. I socketed all 3 builds, and for some reason all 3 sounded better with the 2N5133, a bit more grit or something. Forgot where I got 'em, ran out, now I've ordered more. Could just as easy get by with 5088, but... I like the option of having these...
Cool lookin too, even though that means nothing.

Sorry, I'm OT.

definately agree with the low hF, but $1 is very cheap considering its 6 bux a piece from the store here.

Please don't start this again. You have no idea how many transistors I need to go test to get to that single one that you can purchase from the store. Not to mention all the other things that are involved in selling these.

oh, i wasnt complaining or anything, actually its kool that you have em considering how hard it is to find good ones for stompboxes. i was just saying 1 dollar is much cheaper than 6 dollars.

The truth is I will probably feel better when I run out of them. What a pain to test!

I will probably offer the ones that are lower gain (or keep those to myself - I like the low gain ones). Maybe offer the higher gain/low leakage ones.
