Can I have some insight from those of you who use alternative tunings on your bass. If I used alt tunings I would be confused as to which note I'm playing, since any given fret would not represent the note I am used to playing/seeing. What kind of alt tunings do you use, and how did you come to use that particular alt tuning? How many basses do you play and do you interchange between them? If you have more than one bass, how many of them do you tune alternatively? With your alt tunings, are all your strings still tuned in 5ths? While using alt tunings, are you fully aware of where you are on the fretboard (ie each note played), or do you visualise 'shapes' on the fretboard? For example, if your regular bass broke down and you were handed a bass with normal tunings as a last minute option, would you be able to adapt your playing to regular tuning or would you absolutely have to re-tune the strings before you can 'find your way' on familiar ground?
