Used them 3 times so far, on different guitars. Great tone , great feel , Cheers !
This is my first time trying these. I've also tried the regular light and medium light. Overall, the half-pipe strings are like a semi-light set of strings. The 0.53 is the same as a light E bass string, but the A (0.43) - is a tad heavier than the regular light A (0.42). Then the rest of the strings (D,G,B,E) are all 1 to .5 less than regular light. They still sparkle and have given my old Gurian guitar a different feel, achieving some good bottom end and a tad easier to finger pick on the top. I'm enjoying these half-pipe strings!
