Why don’t you make “X” gauge string?
We make a lot of different string gauges—over 100 actually—and with all companies there are certain limitations in terms of how many gauges we can keep in stock, fulfill in a reasonable timeframe, and ensure that they aren’t sitting around our shop for too long before they ship out.
As such, we’ve chosen the gauges we do make intentionally in order to satisfy the needs of as many players as possible. Unfortunately, we aren’t able to make any gauges that we don’t currently produce as a one-off, the costs of setting up a new gauge for manufacture are very high, and it only washes out when we produce enough of them—if we were to make a 6 string set all out of gauges we don’t regularly make, it would cost hundreds of dollars—for one set. Nobody wants that.
