Alright, i think i have figured out what the problem is. I decided to switch to thicker strings (.011, and the tremolo block went up, you know, so it was no longer in contact with the body, because of my new strings. So i tightend the screws at the back of my guitar to pull my tremolo block down, and i had to screw the screws almost all the way in to get the tremolo block completly down. And after i've done that i noticed increased sustain on my g string, on the 7 fret up to the 12 fret the sustain was fine, above the 12 fret the sustain was terrible and below the 7 fret the sustain was just as bad. It is like this on my g b and e string, but on the thicker strings ( D A E) the sustain is fine.

Help me! What should i do?


sounds like its a neck relief issue. 0-7 are bad 7-12 are good and 12-21 are bad. judging from that i'd say the neck is too straight and the neck needs shimming indicated by the 12-21 problem. The symptoms alleviated a bit when you put 11's on because the added tension caused the neck to concave a little which is what you want.
loosen the strings off (completely slack) and loosen the neck bolts, inbetween the heel of the pocket and the neck right on the edge of the heel, after the last 2 screws insert a slither of cardboard about 4mm wide and 50mm long. re-tighten the screws and re tune the guitar. remember with shimming a neck not to use a thick shim, 1 or 2 mm thick shoud be ideal. A little shim at this end makes a huge difference at the headstock end so be conservative.
now you need to re-adjust the string height, once you've done that you should notice a marked improvement between frets 12-21. If not slacken the strings off and remove the shim.
If it does improve but frets 0-7 stay bad you need to slacken the truss rod off a bit. with the strings intune turn the truss adjuster anticlockwise 1/8th of a turn and leave your guitar to stand for 20 minutes. then play it and see if its improved, if so but its not enough repeat it up to twice more.

I really dont reccomend you try this stuff but take it to a tech and maybe mention the neck shim and truss adjustment to them.


Nice, maby i'll try that, i just have some questions first. What do you mean with "0-7 are bad 7-12 are good and 12-21 are bad"? And what does slither and shim mean?

slither means thin or slim, just follow the dimensions i gave 4mm wide, 50mm long 1-2mm thick.
The shim is that piece of card or i sometimes use leather (depending whats at hand) used to increase the neck angle.
frets 0-7 are bad sustain, 7-12 are decent sustain and 12-21 are bad sustain, not because the frets are bad but i think because the neck is in a bad shape.
Really DONT do this yourself, take the guitar to someone and mention it to them.

I think he's talking about feedback instead of sustain.
Even the most lemon strats i've played had more then 2 seconds sustain.
Maybe a guitarplaying friend can help him sort this problem out.
Have you checked the nut slots, they could be too low ?

I'd take it to a tech. Then I'd get a compressor. And remember, Jimi was using a Marshall cranked to 11.

I noticed now that my neck is really straight, too straight. And when i tried to adjust the truss rod i feel this extrme resistance, i can't adjust it. I tried both ways and nothing happends no matter how hard i try.

I think you really need a tech man. Either your expectations are way off or your guitar is FUBAR beyond your skill. We can't help ya and you don't seem to know what you're doing. Save your guitar and take it to a tech. No offense meant man, but that seems to be where you're at. :oops:
