Honestly, what were they thinking when they designed the bridge system? I own two 5-strings- a Thumb BO and Fortress One. When I bought the Thumb, it was (and still is) strung with Dean Markley SR2000's. The Fortress still has the same mystery-NPS-taperwounds on it from when I bought the bass. Here's my gripe: Even after filing the bridges on both basses to fit untapered B and E strings, nothing fits! I've tried D'Addario XL Nickels (my favorites!), DR Long Necks, and DR Hi-Beams, and nothing works. Either the string is too fat for the bridge saddle, or it won't bend at the tuning post and go through the nut slot properly. The only strings I've found that fit are Warwicks and SR2000's, and I dislike both of these. What else should I do/try? What do you other Warwick 5-string players use or do to your basses to make them accepting of strings?
