Diodes?

[Mr Wright]

What are the pink and orange diodes in Ceriatone's "Yeti" plexi's layout?
Are they used for diode clipping or something?
What kind are they?

The layout is on the Ceriatone site under the 100w yeti

Selectable diode clippers at the input to the volume pot feeding the tone stack. Likely two different Zener voltages.

Thank you sir!

I need to read up more on diode clipping, zener diodes, and how to choose appropriate voltages now.
