As an example, I've been using a set of 9-46's for E standard (Ernieball Hybrids if anyone is interested) and 10-50 for D standard (usual 10-13-17 plain for the treble strings then custom gauges for the bass strings, again Ernie ball nickle-wound). The question is tackling Eb standard. For strings 2 through to 6 I can customise the gauges to my preference however the first string is more of a problem as there isn't a halfway point between a 9 and a 10. Do I go a little on the loose side with the 9 or on the tighter side with the 10? What are your preferences, do you just deal with going tighter?
