My friend has an Ibanez.. something, and it's not the most expensive guitar. Nevertheless, it is a pretty good guitar for its budget. Lately there have been a few problems with it, which I told him I would do my best to fix.
First off, the pickup selector crackles when it is switched, I assume from being dirty because it hasn't done that in years past. I took a look inside of the guitar at the selector to see how to clean it, and it's a sealed unit. I have been reading online and they have suggested something like compressed air or contact (electrical) cleaner. It also said to spray the air in while working the pickup selector back and forth. I would be willing to test one of these out, but if there are additional tips that I should know I would be most appreciative.
Second, the guitar will just not stay in tune (I've learned that guitars are never truly in tune, but it isn't the same thing.) We have tuned it to a-440 with a chromatic tuner, but.. say I play a G chord, the B or another string would be a little bit out of tune..so I tune that. Then I could play an E, then it B sounds out of tune...But if I tune the B, then the G might be out.. I an thinking that this problem is due to A) incorrect action, which I can fix, or B) (my guitar doesn't have a whammy so I don't know about this one) The whammy unit / springs could have been stretched out over time and just won't stay in tune now.
Once again, any help is greatly appreciated =)
P.S. No, the strings aren't new, and they're not that old either.
