I remember my teacher's teacher, who was in a good position to have worthy perspective saying," I love to play on guts at home, but for the (orchestra) gig, I use steel. If two people show up for an audition (for the orchestra), the one playing steel will always win the job."
So, here's the question. I loved the soft feel of the guts and I dig the jazz/pizz sound. Is there a division line between guts being desirable for pizz vs. arco work, in your collective minds/experience?
Eric -- Your teacher is probably correct. In modern-day orchestras, practically no one uses gut strings (if anything, maybe metal wrapped like Oliv). Orchestra sections are mindful of tonal blend, gut will stick out, and so that reinforces the custom.
Gut is certainly bowable, and in days gone by, gut was the only option. But I have to agree that steel strings both sound and respond best for arco work. Bowed gut can be nasal, scratchy, and midrange heavy sounding. They respond slower and require a different touch.
The ideal orchestral steel strings are usually not the best ones for jazz pizz either. A classic orchestra string, Pirastro Flexocore, is pretty dead sounding for jazz pizz, but smooth and beautiful when bowed. Spirocores are the classic jazz pizz stings with nice sustain and clear high-end, but many complain that they can be scratchy or whiney when bowed.
For double duty, arco and jazz pizz, the synthetic core strings like Obligato, Evah Pirazzi and Velvet Compass are a good choice.
IMO, the ideal for a bass player would be to have 3 basses
