The gauge I have is .009/.011/.016/.026/.036/.046/.062 I have a couple of guitars, 5 string bass. Everything is tuned to Drop B. At the moment I am tuning to Gb B Gb B Ab E Db It actually doesn't feel too bad, I sense any lower with that low Gb it'd be flab. Can anyone give me some tips so I can keep everything in Drop B? Cheers.
