: hey guyz!
: 16yr old bassplayer here, im looking to try to reduce the fretbuzz of my j bass, by the way a couple months ago i played a gig outside and it was pretty cold, i was wondering if that had anything to do with it, please e mail me to help out!!

: put another dime in the jukebox baby Sounds like the releif in the neck may be too low.There needs to be enough space for the strings to move freely.Too little releif or bow = fret buzz too much = strings that are harder to fret.Being made of wood,if it is,is suseptable to temperature and humidity.It's not uncommon for necks to raise or lower a little over the course of time Going from winter cold to summer heat and changes in humidity causes the neck sometimes to raise or lower.The neck probably has to be raised a little for the strings to clear the frets to eliminate the BUZZ.First you might check the screws that hold the neck to the body are tight.Also check the screws that anchor the bridge to the body ,thus eliminating looseness or slack elsewhere.Neck releif is adjusted by the TRUSS ROD .A metal rod that runs the length of the neck,inside.One end is fixed,the other is threded with some sort of a nut.The exposed end is at the head stock,just behind the nut.Usally it is allen or hex key of a specific size.If in fact the neck needs to be raised,you may attempt it by; Slack tension off A/D strings and care fully remove them from the nut slots,keeping them aside from the truss nut area.Care fully insret the the allen key into the nut.Remember this if looking down the neck from the headstock,turning nut counter clockwise,loosens tension on trussrod,allowing neck to raise or bow up.(which is what you want).Turning clockwise will increase tension on truss rod,causing the neck to lower more.(Wich you don't want in this case).Only a slight adjustment is nescesary!Make a eight or quarter turn only ! You will feel the tension increase as you tighten.DON'T OVERTIGHTEN!, THIS MAY CAUSE THE ROD TO BREAK and you don't even want to go there.Better to take the bass to a pro repair shop if you don't want to attempt it.A little light oil sprayed on the nut will help in turning the nut.After adjusting the nut,replace the A/D strings in the nut slots,and retune all strings up to correct pitch.You may have to retune again while the neck settles to the new tension.Make slight adjusments remembering that the strings at correct pitch will bow the neck out too.It's all a balancing act.There are specs for this which i am unsure of but it is also a matter of how you want it set up to feel.Bottom line you want the neck to be comfortable to fret and free of fret buzz,the length of the whole neck.If you find you loosened too much ,reverse the steps.It may take a few days for the neck to fully settle so chek it again .Sighting or looking down the neck from body to headstock will give an idea of the relief or by looking at the neck from the side.Before doing all this and if the neck appears to have enough releif,check the saddle height on the bridge just incase they are too low and adjust if nessecary.other tips ;keep your bass in a case when not in use(a bass needs a safe place to live too).Store away from extreme heat or cold.Be aware of how temperature and humidity can effect neck releif. Hope this helped
