Volume loss

[Monopolist]

I own a MIM tele and have a problem with it. The high e and b string now is almost inaudible. The other four strings are all right. Just the two lowest strings. I switched to different pickup selections, tried it on different amps, tried different strings, same results. When strumming chords or playing lead lines, I can't really hear the thinner strings!

Anyone heard of this problem before? The guitar was fine (actually perfect) before. I didn't change the pickup height or mess with the wirings at all!

Really need some help. Not sure what the problem is. Thanks in advance.
