I have two basses. One is an Ibanez SR700 4-string, and the other is a Schecter Damien 5-string. I've used Elixirs, Ernie Ball Cobalts, and Dean Markley Blue Steels over the past two years of playing bass. The Elixirs were the best of that group cause they lasted about 15 months and probably could of gone longer, but I didn't like the looks of the shredded webbing where the picking takes place. The Ernie Ball Cobalts only lasted three months before a string broke in a very low tuning. I liked the Cobalts sound and feel. They are good strings if you can get them to last at least six months. The E string produced a seductive tone that really pleased my ears. The Dean Markley Blue Steels were good for the price, but after I broke a string after three months, I decided to keep looking for stronger strings. Well, I finally found the strings that totally please my ears. Each string has a thick bass tone that is double that of the above listed strings. I have these on my Ibanez now. For all the other strings, I had to max the low on my bass. Now I have the low turned only halfway, and it is still pumping out more bass sound than the others did at full blast! I am amazed with these strings! They are the LaBella Deep Talkin' Flat Wound Bass standard sized strings. My band was very impressed with the strings. We play hard rock, and I heard that flats wouldn't be good for Rage Against The Machine, but it sounded great to us. The strings don't produce the grand piano tone that you hear from many bands like Green Day, but it is not a problem. The LaBellas are pure bass tone that kicks ass!!! I just got those strings, so I don't know if they will last as long as I want, but they should last a long ass time and get even better sounding with age. That's why I chose those strings. Plus, I heard someone say they had a set last them for the last 40 years! LOL I got new GHS flatwounds on my 5-string, and they sound surprisingly good too, but they don't have quite as much thick bass across the board like the LaBellas do. The flatwounds feel a little different compared to roundwounds, but after a few minutes I got comfortable with them. They are a little sticky, but that is supposed to get reduced over time. I have tacky warm hands, so the strings may not feel so sticky to others. If you've never tried LaBella strings, you definitely need to if you want to improve your bass sound! Have a good one!
