I'm new and would like advice

I have a Sunn Mustang guitar that has worked alright for me for the better part of 10 years, but I got it second hand and many of the parts are rusted, and the knobs crackle, and probably has other problems that i dont even know about, how can i go about resolving these problems?

Do any of these problems actually affect its playability?

Hmmm not as such, just it looks like a bit of a rustbucket. So you think I should leave it as it is?

Isn't that the trend these days?

What rusty guitars? I guess i don't have to pay to have that effect then :P

leave it as it is, a bit of wear and tear adds character

Yeah i guess. I'd still like to change the volume without it going CRCKZKZKZKZKSHHSHHCHZ

Edit: right after i wrote that i turned its volume and it worked fine >_< damn my guitar has attitude

If it's the Indian made Sunn, with a ((O)) logo, rather than the Chinese one with the prancing horse, it's actually a decent little guitar considering how cheap they sell for. You can get rid of the scratchy pots problem next time you re-string. Unscrew the scratchplate and turn it over. The pots have a tiny hole in the casing. Get a water-repellent spray lube (I don't like WD40 but it's that type of stuff), fit the little plastic straw on the nozzle and spray into the hole. That'll blow out the grit and relube the metal.

Failing that, you could buy some new, CTS, 250k pots and solder every wire back as they were onto the new pots. Bearing in mind your Sunn can be bought for around £50, you don't want to go much further than that.

The crackeling in your knobs is the result of dirt in the pots. Go to your local electronics store and ask for some electronics contact cleaner spray. It should be about $15 a can.

I could go watch this video.

As for your Rusty parts... well?!! I've had some success with super extra fine steel wool and a very light hand. Use care that you don't get steel wool crumbs inside your guitar. Otherwise use a dry stiff toothbrush to brush away the rust scale as best you can and then everytime you change the strings be sure to clean and polish the metal as well as the wood. (I've also use a very fine jewelers rouge to polish and remove small spots of rust)

Thanks for the yootoob link, Sylvia. I had a look at it and was mildly disappointed. I didn't mind that he cut out the screwing, even though I can happily watch someone screwing on a yootoob postup for several minutes, but the aim for the spray from his nozzle wasn't all that accurate, either.

Coupla points: there are two types of contact cleaner spray; the "no residue" type like Blow-off and lubricating types like DeOxit. Blow-off is good for non-moving parts like sockets but they are bad news for something like a pot, which has moving-metal contact and requires a bit o' lube.

Secondly, that demo had the guy gingerly lifting the pickguard like it had live cockroaches in the routs and spraying in the general area of the vol pot. Much better to turn it over properly and have a good look at the little scratchy. All pots have a tiny hole and you should aim the nozzle right into this to do the spraylube job properly.

Granted the vid wasn't perfect but it was provided as a brief guide, since some folks are visual learners. I think the reason he was lifting the pickguard so gingerly was to protect noobs from yanking and thus breaking the soldered connections and not that he was afraid of cockroaches LOL!!

On that point, I recently replaced the pickguard on my strat and found a Cheeto and a small allen wrench in there. LOL!! :shock: WTF!! I guess you'll never know what you'll find when you open one up.
