Okay..I know how to Drop D tune. That's pretty easy to do. Just hold the 12th fret on the 6th string. Pluck strings 5 and 6 and keep lowering the 6th string till the sound stops clashing. But how do you tune to a Drop A, or C tuneing. Like in Chevelle's song "Clincher". there tuneing goes as this.

Tuning: Drop A# (A# F A# D# G C)

I have two eletric guitar tuners. But they just have 5 lvl's of flat. I didn't see in the booklet anywhere if this is also used to Possibly drop tune. Any advise would be greatly appreciated. Thanks! Rock On!
