Ok guys I think I've done the necessary reading...... I have never owned a bass strung with guts and am really ready to give it a try. There are so many different strings to choose from and I am not sure what to try first and I'd prefer not to have $1000 worth of string just laying around for testing. I currently play a Kolstein Hybrid bass strung with Heritage bass strings. When playing out I mostly play pizz jazz but I'd also like to get involved with a local orchestra which I might do soon. My point being I want a great sounding pizz jazz string but I don't want it to make my orchestral/acro harder or less desirable. At the moment I spend allot of time practicing scales and etudes with the bow and I don't see this changing anytime soon. What sparked this? Well I went to see the Ron Carter Nonet over the weekend, suprisingly enough I was super impressed with the bass player in the group, he played a set of Guts and it sounded great and it made me realize how much darker and nicer he sounded especially on the upper strings. Can't say I loved RC's amplified sound but he was still great and that's another story for another day! The teacher I am currently with plays Animas but he has a bass specifically set up for jazz playing and didn't seem to love the them for all around playing. Thanks for the help!
