Mike, It's been several years since I did that particular Chickering. At the time, I was either using Mapes or Schaff. (They be the same now.) I do not use them now. (Don't ask!) The current Bass string makers, I use, are Ari Isaac and J.D. Grandt. Both, are in Canada and do an excellent job. They will work with you, if you need something special. They can read a "Scale Sheet" without screwing it up! They BOTH take pride in their product and back it up with SERVICE! (An aside: BOTH are visually impaired! Yet, they make excellent strings! IMHO, no impediment there!<G>) They both are very knowledgable in regard to scaling, as well. I hope this helps. Best Regards, Joe Garrett, RPT, (Oregon) Been There, Didn't Like It, So I'm Here To Stay! [G}
