How can I tell what string gauge I currently have on my guitar? My Low E right now is only 1mm (approx. 0.04inches) in width. What gauge is that as in Extra Light, Light etc.
As far as gauges go extra light and light can differ from brand to brand. I doubt you're gonna be able to find out what size your strings are. But if you can play a couple of guitars with different known gauges you may be able to guess.
you have an 8 gauge super light string on right now, I advise switching to a ten gauge but to each his own
