Tuning Systems - Which do you use?

The double bass is by far the least-standardized member of the string family! Our instruments come in all shapes, sizes, and even tuning systems. On the tonebase platform alone, we already have artists demonstrating in four different tuning systems! 

- Orchestral Tuning (G-D-A-E)

- Solo Tuning (A-E-B-F#)

- Fifths Tuning (A-D-G-C)

- Mixed Solo Tuning (A-E-B-E/C)

Have you experimented with multiple tuning systems? Or systems other than the ones we have here (such as Viennese tuning, or High-Solo tuning)? 

Please take a moment to tell us about the changes you find, advantages and disadvantages, things made easier or more difficult!
