Distortion + and diode selection/identification

[matopotato]

I am working on a project based on Distortion + and Jack Orman's muzique.com site (http://www.muzique.com/schem/mxrdist2.gif) with different variations of saturation control (http://www.muzique.com/lab/sat.htm and http://www.muzique.com/lab/sat2.htm) and asymmetrical clipping (http://www.muzique.com/lab/warp.htm)
So then I have several candidates to work with:
1N60 Ge
1N4148 Si, kind of standard
1N5817, didn't expect anything, but they are quite interesting (IMHO)
Red LED, gotta have them since they will light up with maxed controls which will look cool

I dropped Zener 5.6V/0.5W since I did not feel they gave me much
1N4004 didn't do much or different than any of the other settings.

My question is, what can these be?


The grey-green striped show ~220mV. And they sound very nice
The black-red-red striped also sounds nice, a bit stronger. They measure ~550mV
Both pairs are from an Ericsson Dialog phone from the late 80's. Neither have any text on them.

Just a guess, but .220v suggests schotky. They do sound nice.

Thanks. Yes they do.

Anyone with any thoughts on the Red Red Black striped, or any identification site on internet?

550mV is not outside whats to be expected for normal Silicon transistors, could be a proprietary version of something common, like the 1N4148

Thanks, yes I tried them onbthe same board as 1N4148s that read about 700mV, so the pairs do sound different. But probably more due to Vf then.
I got them from desoldering an old Ericsson Dialog phone late 80s. And it had both 4148s and these unmarked ones.
