I'm pretty particular about my string gauges and there are no sets in the gauges I want, so I'm forced to buy my strings as singles. Problem is, there's always one gauge or more that's missing even from the singles, depending on brand. Like maybe there's no .040 from brand X but then there's no .030 from brand Y. So, what would happen if I were to get say some D'addario, some Ernie Ball, some Elixir, etc.? Would it be noticeable in feel, sound, etc.? Anyone tried it?
