These are my initial impressions:
They arrived saturday, and I installed them sunday. It was not as hard as I thought it would be. I had to use my needlenose pliers to hold the ends through the tuning peg holes, because they would slip out. I put about 4-5 wraps around, and then cut the ends with strong clippers. The clipper on my pliers was not strong enough, which was a good sign! The whole process took about an hour. The strings themselves looked and felt like the top three strings of a nylon acoustic guitar, only much thicker. The same thickness as guts. Once I got them on, they seemed to have the same pitch and tuning problems as guts. No worse. I immediatly started practicing on them in a band situtation, and I was very, very impressed. The tone was almost exactly the same as guts! Warm, deep, even articulate! In fact, my ears could not tell the difference at all. The tension was as low as guts, and the only difference really was the slick feel, which I have heard you can rough up with sandpaper. As far as I am concerned, these are the strings I will use on this bass from now on. Keep in mind that I am using a piezo pickup (K+K bass max) and am not playing classical or modern jazz. I am using these strings for roots music. I would not advise using these for arco, or in an orchestra or baroque setting. My band plays traditional hawaiian, western swing and folk. These strings are the most incredible things I have ever played since guts. I only wish I had made the 20 dollar investment sooner. I just ordered 4 more sets this morning! The value is obscene, as these strings will more then likely last a few years, and by all accounts, only sound better and hold their pitch more in time. Barefoot larry seriously needs to consider selling these things at all the major music chains, as they are perfect!!
PS, as of this morning, they had only dropped about 1/4 a note in pitch, and only two of them at that. The other two stayed perfectly in tune. I am sick that I payed 140 for metallic sounding Eurosonics, and had thought about other gut substitutes. IMHO, metal will never sound or feel like guts completly, but these things sure do! I will never pay 300 dollars for guts again. I will post if there are any changes soon with the sound, feel or tone!
