“That top nut is probably the most common problem with any lower-end mass-produced guitar”: Having problems with your shiny new guitar? Try these fixes first

Fixes to make if your new guitar doesn't sound right: from tuners to tremolo units, nuts and string trees, many new guitars need some TLC to make them sound at their best.

You’d hope that when you buy your shiny new guitar, it would be perfectly ready to go, especially since guitars aren’t getting any cheaper as we’ve all no doubt noticed. Over the past year, however, it’s fair to say rather too many new instruments aren’t quite finished when they turn up at Guitarist HQ.

Is that acceptable today? Do guitar companies think we should either spend our own time finishing off their guitars or pay a professional? Is the quality control of new guitars going down the pan?
