Normal and hard tension
(thank god we don't have to deal with gauges as in case of electric guitar
Rahul, I agree with you, but I also think that most electric guitars play reasonably well with whatever strings are used, heavy, light, super slinkys, etc.
It depends what electric sound you want.
With classical guitars, I feel that they are different beasties. They can be very temperamental and sensitive to what nylon strings are used.
I am amazed at how bad mine can sound with one manufacturer's high tension strings, and how good with another's.
Yet, it would seem that the strings appear identical in construction.
All the good music has already been written by people with wigs and stuff.
