Notes too low on sheet music for bass?

Usually, notes for the bass guitar are written an octave above where they are played, sometimes with the note to play "8va basso", or some such.

I've searched all over online both on Google and here at GN... I can't find anything that can tell me what to do about notes that are too low on the bass cleft for playing on the bass. Is there a way to transcribe the notes to a playable range? Can anyone help? :(

As I don't know what you're doing with that bass part, these options might be completely useless - but I'll mention them anyway.

1. You could move the section of the passage containing those notes up an octave
or
2. Transpose the whole thing to a different key
or
3. Tune the bass down

Well, I have Bach's Cello Suites. They go to a C below the staff, while bass goes to an E below the staff (I'm naturally playing these an octave down). I just put my bass in cello tuning, CGDA. It makes actually playing the song easier, too.

I transposed it going up a higher octave and it works perfectly. Thanks!
