Absolutely bizarre fret buzz issue - help please!

    On my 2002 Lakland Skyline JO four string, my G string buzzes on the 7th fret only when the E string is fretted as well.

    I noticed this when running up the G scale with added thirds and it doesn’t happen anywhere else on the neck. Only the 7th fret D on the G string when the E string is also fretted at the B on the 7th fret.

    Bass was recently set up a few weeks ago by an experienced tech, whom I trust, with DR Hi-Beams. Haven’t noticed this until today. I recently also added a large humidifier to my guitar room if that makes any difference.

    Any ideas here? Should I raise the action?

    Edit: Could this be a frequency thing? No other note on E, A or D within reach causes the sharp buzz.

    Neck might not have enough relief? A sort of reverse buzz can occur between the string length between the nut and the fret if the neck is too flat.

    I would try raising the g's saddle a smidge and see if it works itself out, if so and the action still works for you just play it if not check your relief as cxcxcx mention try adding some relief. Have you put a straight edge on the board to see if you have a high fret?

    I was thinking - if you tie a piece of old, clean t-shirt (Something that won’t damage your bass) around the 5th fret, it will dampen the string length between the nut and the 7th fret. If you try to get the buzz like you have been, and hear no buzz after tying the cloth on, I may be right about not enough relief.

    Relief seems fine based on my eyeball and using my wife’s scrunchy to dampen the fifth fret. It doesn’t seem to be a high fret either. Weird. No buzz when fretted alone but when I fret the E string on the same fret it still buzzes. This is driving me nuts haha.

    Thanks so much for your ideas so far folks. Gonna mess with the action a bit in the morning and see where that gets me.

    Have you tried to restring the g? Loosen and redo? IDK make sure it isnt twised? Check saddle springs that particular freq might be causing it to bugout a little? GL

    Does it buzz unplugged? It may be something in the room buzzing.

    Yes it does buzz unplugged. But only when I’m fretting the E. I don’t have to play it at the same time.

    Yes I was wondering if it was frequency related but it happens when I fret it without playing the E too. I’ll try to post a video tomorrow.

    It’s a very common form of back buzz - i.e. fret buzz between the fretted position and the nut. If you fret the E string at the 7th fret and pluck it between the nut and fretted position, the buzzy note you will hear is D. When you fret the G string at the 7th fret, the resulting note is D. That note on the G string is causing the back part of the fretted E string to sympathetically vibrate, thus rattling on the frets. Fret the same spot on the E and simultaneously play an open D string for the same effect.
    The solution is to add a bit more relief or raise the E string nut slot.
