11-56

[Iivari]

These days I play in Drop B (basicly C# + low B) My gauges 10-13-19 or 20 wound - 28- 38 - 56

tonight, I was playing my acoustic for a few minutes(13's), I went to drop b comfortably, then like a Page fanboy tried double dropped b..... Very comfortable!!! I think I'll try 12's on the electric. I've tried using a string pull calculator and to be honest it didn't really work for me. So I'll probably try a stock set to start with and work through trial and error to find whats the most comfortable ~ Thanks for y'alls replys!!!

when Ever I set up a customers guitar for C# or drop C# I use 10-52 just retain tone and tension. Any lower than that i go to 11-56 or heavier dependong scale length and tuning.
