One of my Millennium 5s I bought right here on tb, came with dark gray Will Lee strings of some sort. They are real dull nickel gray...compared to my Cirrus strings I normally use...I think I'll replace just the 4 with my Cirrus strings, and try that. I don't look at the strings that much either, but in the heat of battle, like when you didn't practice quite as much as you hoped, and haven't played some songs in weeks, right on stage, when that panic strikes, you know it, "oh crap, which note is it again?"...the B gets comfuzing.
I do that much more on my 5's than my 4.
I'll give it a shot. It's a cheap experiment. My 4 string is so broken in, that I can't imagine getting rid of it, even though I need and want only 2 basses. I have 2 identical 5 strings, and one 4. So, I really have to go all 5ers, or a mixture. Another issue is my 4 string, the Cirrus, has a much longer neck, at least visually. All basses say they are 35" scale, but there is a noticeable difference between the two models of basses. It's a big enough difference where after a long time with the Millenniums, the frets feel like they are in a totally different spot on the Cirrus. The A on the E string, is about 1.5" farther away on the cirrus. So my hand naturally floats to where the note should be, but it's a fret off. I guess I'm getting old and my brain doesn't like change anymore.
Sorry for the rant.
