What is the deal with those 1n34a diodes that look like silicon diodes?

I like the enchiladas, and the teriyaki too
I even like the chicken, if the sauce is not too blue

If you can't see a whisker through the glass envelope then it is not a germanium point contact diode like the 1N34A or 1N60.
Well that is unless it is one of the real original Sylvania ceramic tube 1N34 diodes in which case you have a museum piece.
Some manufacturers seem to have produced a Schottky diode and called it a 1N60P so that is silicon, not germanium.
There are, of course, some silicon point contact diodes like the 1N23 but those are usually in metal tubular or ceramic bullet envelopes and pre-date the germanium point contact diodes as they were used as detectors in WWII radar receivers.

The 1N23 was commonly used as a UHF converter diode in television sets and standalone UHF converters.  I have one where the diode is held in clips and not soldered into the circuit.  After the early ones, they used a 1N295 that was a common detector diode in transistor radios for both AM and FM detectors.

I know all about the 1N23 and still have some of them as well as 1N21, 1N26, CV2154, CV2155, CV3923 and CV5002 silicon point contact diodes that we used in microwave receivers and ELINT radar analysers during the cold war period. You won't be able to see a whisker in any of those as they are ceramic or metal cased diodes.

However, I have never seen anyone use them in guitar pedals.
