||Neon & LDR in Fender Tremoloes|
What kind of LDR and what neon bulkb were used in old fenders? What would be a good contemporary substitution with the readily available parts?

I ment the tremolo cirquit application.

The bulb looks to me like a NE2, and I just fixed one last week with a photocell that went down to about 1K when brightly lit and up to over 1 meg in the dark.

Thank you Enzo. What about wattage? how many watts should the LDR be? 1/2 as all the other resistors in the cirquit?

In the Twin I just fixed, the tremolo photocell acts as a variable resistor across the signal path. SO there is no current at all, just a few volts of signal. I would get the most sturdy one I could just for physical reliability.
