Classical solo strings make things work better across strings, but that set up is limited.
If you are going to play the double bass with any seriousness you are going to learn at the very least two fingering systems - thumb position + a lower position concept.
And at least two clefs, bass and treble if not tenor AND bass clef at pitch.[\QUOTE]
Do you mean limited in its transference to jazz playing? I'd agree that the
vast majority at this point will learn two systems, but there are also very serious players using one system all over the instrument. (see above
ad nauseum)
You really need to re-think the instrument. While you may end up playing some of the same notes with the same fingers it won't be about retaining bass guitar patterns or technique.
Definitely you need to re-think the instrument. BG technique just does not work on DB. A lot of the BG patterns
can be kept, mentally (even when using a 1-2-4 system as Chris described above), and even physically if you're lucky enough to find a teacher that teaches 1-2-3-4 on DB!
