I have just see this:https://www.northwestguitars.co.uk/truss-rod-adjustment-tool-phillips-head/ It looks like it *might* be just the thing to adjust my JMJ mustang when it needs a tweak, but it depends on whether there's enough room around the pickguard cutout to get it in place. I know that StewMac make a tool that will do the job, but ordering that one from the US is quite expensive in comparison. Has anyone tried one of these Hosco ones?
