| A single truss rod will keep a neck straight (or at least with a very slight bow in it - a truly straight neck isn't properly adjusted) along its length, but won't help if for some reason the neck starts to twist. Twin truss rods can help to resolve this issue, which is why they're typically found on instruments with very wide necks (such as 6+ string basses) where the wood's more likely to twist. However, adjusting the neck on a twin truss rod instrument should certainly be left to a professional, as having the two rods set so they're not aligned can permanently affect the playability (and structural integrity) of the instrument.
"Fast" action means different things to different people, but it typically means that the strings are very low and close to the frets, so you don't have to press down as far to fret the note, thus you can play faster. Adjust the action too low and the strings will buzz. You can typically get a lower action on a more expensive guitar (and always on a properly set up guitar) because the frets should be seated and aligned better. Of course, some people can play a guitar with quite a high action very fast! The radias of the fingerboard can also affect the action - it's generally easier to get a low action on a guitar with a flatter (higher number of inches) radias fretboard, although this also depends a lot on the type of bridge that's on the guitar.

| Good question Ben.
Truss rods should only require minimal adjustments. If you are heavy handed, it is best left to the experts. But if like me you cannot resist experimental tinkering with screws, handles and levers, keep a history log of every action undertaken so the guitar can easily be returned to the factory (or luther's) setting.
I write this log on a small piece of paper and keep it handy under the truss cover plate, or rolled up and pushed into the truss adjustment tunnel found on Stratocaster guitars.
I use a simple code:
C = control or factory setting.
T = tighten 0.5 half a turn
L = loosen 0.25 quarter turn
You get the idea. You can make up your own code. Good luck!

| thanks to all that answered.
i have slackened my truss rod a bit and put a slight bow in it. the guitar sounds brighter and doesn't buzz at the 7th fret now. i only slackened it a quarter turn with the allen key that was supplied. i have writen it down and saved it as suggested.
thamkyou for your advice
