Help: SR300 noise/crackling

    I'm aware this is a subject that's been covered in some detail before, but there are a couple of areas in which my problem is a little different.

    Recently, my fretless SR300 began making strange crackling/distortion sounds when playing a note. It isn't constant, indeed it seems to come out of nowhere when it feels like it. It only occurs when the pickup pan knob is at dead center or towards the bridge pickup, somehow the neck pickup doesn't do it. I've had the bass just under a year and it only started doing it a few weeks/ month or 2 ago, I don't recall it doing this before then.

    I put a new battery in just a few days ago so I know it isn't that, like I thought initially. I've tried 2 different cables to no effect. I don't currently own an amp, I'm playing through a little crappy (but functional) Behringer mixer into my PC, but I don't think that's the problem either. I did open up the back of the bass and aside from thinking "I have no idea about any of this" it didn't look to be badly wired though I could be wrong.

    This is starting to become quite annoying, any help would be greatly appreciated:bassist::bassist::bassist:

    I had an SR300 and after 3 years the electronics started to crack, I solved the problem by oiling the pots, but it came comming up.
    In such cases the electronics simply lack quality.
    From your story I believe it's either the bridge pickup, which I hope not, or the pan pot.
    try oil the pot with silicone spray or similar. If that doesn't help I fear you'll have to replace the pickup and or the pot. Again the quality lacks so if you can fix this, beware that in time other isseus can come up...
    I sold mine anyway, partly due to these problems.

    Replace the pickup? God I hope not, thats far too much maintenance for a cheap bass like this...(yet I still see myself resorting to that somehow, lol), I'll have a go at cleaning the pots soon, just need some of that contact cleaner.

    As an aside, I think I just heard it do it on the neck pickup as well, and both vol. and pickup pan were crackling as I was turning it, hopefully its a simple case of cleaning the pots then...

    I bought my first bass a few months back, and I was looking at this one. Either all the one's GC had were either setup terribly or had electronics issues :rollno:

    I normally have great luck with Ibanez, so I am guessing it was just floor models that had been sitting around since the Jurassic Period.

    I'd say that if you have any electronics experience, pop your head back there and see if there is any bad soldering or loose connections. Otherwise, bring it out to a tech.

    Cleaning the pots helps against the buzz, but it can be that the buzz will return...
    If it cracks louder as you turn the pots it is defenitely the pots, the pickup buzz might dissapear as well.

    Well its in the shop, no bass for up to 2 weeks, and I'll be surprised if its an easy/inexpensive fix ...
