FC detector, or just a good job?

Mis-read the OP. I agree, it might be for an FC without overstrumming.

It's not an FC is you over-strum. It took me a while to get it, but 100% does not equal FC.

FC is short for "Full Combo", which means every note hit and the multiplier maxed-out the whole time with no extra notes or over-strums or extra drum hits. I suppose FM for Full Multiplier would be more accurate, but I guess the multiplier is a combo-meter of sorts.

I get an FC, yet mine won't make that sound unless it's the last song on a setlist.

The little power chord/solo thing I think is 100% on a solo, based on further play.

Granted, I'm not a competent enough guitarist to stably test things requiring FC's, lol (or well, I'd get bored of Master/Slave and Something in the Way really fast) so I'[ve more or less left it to mystery.
