Ice made a decision to put RoundWounds on my 5 string Its a love thing! I took the trendy plunge in to Flats on my Fenders for a year. I put Nordy Single noise canceling pickups on my 2008 MIA Jazz 5er and loved what I heard. Played it with flats for about 8 months, and I'm lining the RoundWound voice. This has been my sound for 34 years and I'm going back. I'll keep my P bass strung with Flats.
