Like many places in North America, we've been having a scorching past few weeks here in Toronto with high humidity. My 610 (6-String) had been in its case in the basement for 2 weeks unused while I'd been on holiday and now that I'm back and playing again I've noticed some pronounced fret buzzing at the 2nd fret with the lower 3 strings (EAD). Sighting the neck, I see its backbowed a little on the treble side - odd considering that its the bass side that's buzzing but then again those are the thicker strings.

Anyway, my question is - should I lightly loosen the truss rod and correct the problem or should I sit out the extreme weather we've been having and wait for the neck to return to its former self? I would prefer not to be making adjustments I may not have to make. My fear is I loosen the truss a little, the weather goes back to normal and I'm left with too high action and will have to start all over again.

Anyone else dealing with this sort of thing with this Summer?

Consider adjusting the neck as an extension to tuning the guitar.

If you're going to play it, then make the adjustments, or no one will be happy.

If you're on hiatus, leave it alone till you are actually going to play.

Adjusting the neck is really not such a big deal once you are used to it. These seasonal/climactic swings are usually only about 1/4 turn's worth and take all of about 5 minutes to accomplish. Just don't be in a rush. If the guitar's been stored in a case for any length of time, leave it out in the open overnight for it to re-acclimatize before commiting to making adjustments.

Thanks for the reply, you've written what I've needed to read!

I'm never nervous about truss rods on my other guitars but I'll admit the double truss is just a mite daunting (then again, I have the proper tool and it is after all a loosening in this case, rather than a tightening - so less of a worry).

Thanks again!
