Thanks for trying this out and for the info. I suspected the LED would sound differently compared to the lamp because of the binary nature of the LED. Sounds like a challenge.
I have all the parts on order to build the Electrovibe and wondered if anyone had tried replacing the lamp with an LED and if this was even a good idea. I Perused the Forum for Electrovibe mods/issues, but no mention of this mod.
Would you please advise me?
