Ring Modulator / Sitar Effect - labeled ValveWizard - Who is he?

[kagliostro]

I've find this small schematic on the web, the label indicates that it is from ValveWizard




despite that I didn't find any reference to it on ValveWizard pages (http://www.valvewizard.co.uk)

it is called Ring Modulator / Sitar effect

There are no other explanation on it and this make me curious

Someone can explain which effect is expected to give to the sound ?

But, more, how this circuit acts ?

Many Thanks
