i just bought a yamaha rbx 374 guitar about a month ago, and of the four knobs, there is one that is very loose. ive read some of the other threads, and ive even removed the back panel, but i have no idea how to 1.) tighten the knob, or 2.) remove the head of the knob. can someone please help?
do a search on this. I just answered a thread like this 4 hours ago. Take a look at the knob itself. Look all around it and there should be a little screw that fits a small allen wrench. Loosen that and your knob will come off to expose the pot. If the pot is loose, screw the nut down. then put the knob back on.
oh thanks dude. i somehow managed to tighten the knob head, without having to remove it. although, i think i should figure out a way to actually tighten the knob itself, since it might lead to problems in the future. thanks for the help.
Ahh the nice fancy looking thing was loose. I got you. Underneath those are what we call "pots" (short for potentiometers in electronics). Those are the ugly things that make the volume go from zero to max. It is basically a variable analog control. When you take off the fancy knob handle you can see how those are stuck on the bass. They have a nut and washer which keeps them in tact. If those loosen, you need to tighten the nut (not too much because it could crack your wood) If you don't then you are right and problems will occur later on. The whole pot spins when you turn it and eventually the wires get ripped from the pot. You should remove the back plate and hold onto the pot you are tightening to ensure that it doesn't move on you.
thanks for the help. i managed to fix it around 2am last nite... hopefully i didnt tighten it too tightly.
