I just found out about these. I've been sending D'Addario messages to do balanced sets like this for a couple of years and they totally ignored me every time. I'm REALLY happy to find out this exists. A few questions before I place any orders: 1. What is the sound like on a fretted bass? I have a Rickenbacker 4003 with 45-60-80-105 Nickel XL strings that are very dead, and I want to try the Long Balanced 106 set on it. 2. What is the sound like on a fretless bass? I have a Rickenbacker 4003FL with 45-60-80-100 Fender Flats (the new ones that are like Chromes) but I'd like to give the same rounds I mentioned above a try on it. 3. On said fretless Ric, will these strings beat up the bubinga fingerboard? So far (I've gigged it for two years but always with flats or half-rounds) it's been impervious to damage. 4. What is the feel like? Very stiff, very noodly? Harmonic character? Compare to medium gauge typical rounds.
