Hello Talkbass
I´ve been lurking around for some time now and really appreciate this worldwide community of double bass players. I ve learned a lot (not only in the strings section

). Thank you everybody. I just felt I need to add my 2 cents to this gutfiesta.
A month ago I decided to order cheap guts from Efrano (heavy G, medium D) and after putting them on thought immediately "This is the way bass is supposed to sound like". I had tried various different steels and synthetics before, but was always hesitant to try real gut because of the tuning issues and bowability. The guts replaced the upper strings of a Velvet Blue set.
After a couple of concerts, jam sessions and rehearsals (blues, latin and other mostly pizzicato stuff) later I can say that at least for my needs, this combo really works. The pizzicato sound is really loud, fat and percussive. The tuning has been surprisingly stable (maybe the Blues on A and E help there) and, after a bit of practice, arco is doable, the stings start quite nicely and I like the grainy old school sound.
Maybe the most important aspect is that the sound of my bass really inspires me to practice at home, the room is shaking and rattling. Guts really are fun to play.
Best Regards
PS: I hope you won´t find me too soon in the Evah pirazzi megathread...
