Guess I was gone surfing the day they discussed this one in grade school, and never paid enuf attention since thinking all along it was with an e, until taking pix of my new Strat and noticed the Fender headstock spells it Tremolo.
A quick search has plenty of both uses, but with more proper evidence of it being TREMOLO.
