Here is an example that I think sound really cool for a slow song. Can be used as intro or ending.
It uses the Cpedal and a full tone raise on the 7th string in combination w the E's to Eb lower.
Make sure you note the half-raise on the 7th string noted as ---8R---, the full raise is noted as ---8RR---.
Just pick the first 4 notes and let them ring.
The C-pedal and levers does the magic.
