I'm re-stringing my Spector E-F (as opposed to B-C) the problem will be getting the high F string. 7 string sets are darn hard to find here and I'm not ordering off the net. I had the idea of buying an 8 string set and useing the 4 normal strings and 2 piccolo ones for the C & F. The average C string is 0.032, and I was wondering if a 0.04 or 0.028 C string would work well, keeping in mind this is a 35" scale bass. I'm thinking of using the piccolo G (0.018) for the high F, will this also work? And will the D'addario long scale EXL 170-8 strings fit the 35" scale Spector? Thank you and I apologize if this has been discussed before.
