i have a suzuki fg700s that buzzes a little bit on the low strings until the 5th fret. i was wondering if i need a truss rod adjustment.. if i do, i was wondering where i adjust it on this specific guitar.
To check and see of the trussrod needs adjusted put a capo on the 1st fret and then push the low E string down on the 14th fret. Now look at how much air is between the string and the 7th fret. If it has less than about 2mm then you might want to loosen your truss rod. If there is 2mm or more then it's more likely that your guitar need a fret dressing.
Not taking any online orders.
that sounds like you need to loosen the truss rod (i assume that you mean the 1st, 2nd, 3rd, 4th frets buzz, indicating an outward bow)
