Well ive only had it about a year. Its a shecter 006 Deluxe with Stock Pickups and when its on the gain channel and I play somewhere like 12th fret High E string...it makes a like a mass amount of tremolo is on..its only from like 10 to 16th frets it does it. I can make a sound recording if that helps.
Passive pups may lose some magnetic pull after like 30-40 years so I doubt thats your problem try it thru another amp, thats more likely your prob.
It's odd that your pickups would be dying already.
but it doesnt do it on clean.
so the dirty channel on your amp may be crapping out, take it to a store with Line6s and give it a listen. and only use good cables.
What he said
I got monster cables
It happen the same to me at the same frets and the same string, but only with the neck pickup. I have a strat copy (Biscayne Flyer Ltd). It sounds like you were playing 2 notes with distortion at the same time, isn't it?.
