What is this component? Answered

I am wondering if this is a special component or just two diodes, and i am also wondering what the "Si" means.
Thanks,

According to your description under "Related" and the partial diagram, they are individual Silicon diodes. They are used to chop the top and bottom of the signal to produce the "fuzz" in a fuzz pedal by cutting the signal to (approximately) plus/minus 0.7 volts no matter how large the signal. The larger the input signal, the more signal is cut off and the more "fuzz" you get.

Looks like a cutout of a 4 diode bridge using Silicon.
Or a voltage multiplier or an input limiter to an IC like an Op-Amp or uP.....

its definately two seperate components in any case and Si again is silicon

looks like it could be an ldr (a componeot used in light sencing cuircuits (sorry if yot8 knew)) but as others have said the view we have of the diagram isnt enough to see it propperly hope i helped

Without seeing the surrounding circuit it's hard to tell. Possibly a current-limiting device. Maybe not.
As per rickharris, Si is the symbol for Silicon (he misspelled it as silicone), but that really doesn't tell us much.

It would help to include more of the schematic that it is used in, to get the context of how it is being used. Based on the image alone, it looks like either two diodes, or perhaps the equivalent circuit for a dual diode component.
