My main concern is if I went to the lighter DR lo-rider's, guage 40-100, if I would lose any or allot of the tone you get with 45-105. I know allot of you guys use DR's, and experiment with guages and tones, and was hoping to get some help on the subject. I have to special order my DR strings, because no one stocks the nickel plated lo-riders in Saskatoon. I have heard people say they prefer the sound of a lighter string, and some people have even said to their amazement, that their lows have been brought out more by going lighter. I'm thinking of using the lighter guage because after playing a friends bass, with a lighter guage string, I found the playability to be more to my liking. The problem is that I love the tone of the 45-105's, and need to know if I'm going to sacrifice any thump, or bottom with 40-100's? Will the tone be brighter, thinner, bigger, heavier, or will the change to a lighter guage of DR lo-riders be barley noticable if not at all?
