I am toying with the idea of trying an alternate tuning on my 6'er (34" scale). It would be three half steps up from standard, so D-G-C-F-Bb-Eb instead of B-E-A-D-G-C. I'm looking at building a set of strings, and here's what I'm thinking, gauge-wise: .120, .090, .067, .050, .035, .025w. I "built" a set using these gauges on BassStringsOnline, with D'Addario Nickels. I also saw a balanced tension set of Circle K strings that had roughly the same gauges. I am trying to avoid using an unwound string for the highest string. Has anybody tried this before? Will I run into any tension issues (I prefer a lower tension)? If this doesn't work I might just string it up like the highest 6 string of a 7-string bass, E-A-D-G-C-F, using a plain unwound string for the high F.
