Location: Tampa, FL | So I own a 2078T (as some of you know :) ), and I just moved from light to medium gauge, so now I need to adjust the rod... the action isn't so much bad as it is inconsistent, since it's warped a little bit.
But in any case, here's what's up. I occasionally hammer away on this guitar, so I can't afford to have any fret buzz, so I'm not looking to adjust the saddle and everything to get really low action, I just need it to compensate for the gauge change.
The book that came with the guitar isn't very clear, so I figured I'd ask on here. When I open up the back, and I'm holding the guitar with the top facing down, there is one nut facing down (up if you're holding it strings-up), and two facing towards the neck of the guitar. Which of these do I turn clockwise to get this to work?
I figured I could try, but I'd rather not mess up something.
Thanks.
(And yes, I know I could go to a good technician, but I don't know any around Orlando (just moved here from college), and would rather not take it to Sam Ash or Guitar Center to have them do it.) |

Otherwise, it will be an allen key bolt which faces towards the bottom strap button (i.e. directly away from the neck when you are inside the bowl).
I'm not an expert on this, but most people say that shims are for adjusting action height and the truss rod is to get the neck straight. |

Location: Hot Springs, S.D. | If you've gone to medium from light strings, the increased tension will cause the neck to warp a little. Whether the truss rod adjustment is in the peghead, or inside the body, remember: "righty tighty". So you need to turn no more than a quarter turn at a time, to the right. You should leave it overnight, even if a quarter turn doesn't do the job, because as it sits overnight, the wood on the neck will slowly move in response to the truss rod adjustment. The next day, (or even the day after) if it still needs tightening, repeat the process. |

Location: Tampa, FL | The adjustment is inside, not on the head.
And now looking at it from the end, the headstock of the guitar definitely needs to come down to get even with the whole thing - the strings are close, then get far away, then close. So it is warped a little bit, so I'll tighten the truss rod a little tonight and figure it out from there.
Thanks. |

Location: Tampa, FL | Note: the nut facing straight away from the neck of the guitar could not turn (at least not with my strength), but the one facing the roundback could.
So I take it that's it. It does make sense when I look at it. |

If it's internally adjustable, it's a Kaman Bar and the truss rod adjustment would be the hex nearest the top/fretboard.

If for some very weird reason it does not, and the adjustment in inside the bowl, and it has a Kaman Bar... Make sure you adjust the allen bolt for the truss-rod. If you adjust one of the bolts this hold the neck on, you get This!
But a 2078T should have a Truss Rod Cover on the Headstock! :confused: |

:) This makes no sense to me....
Are you saying the head of the bolt points to your belly if you were holding the guitar in playing position? |

Location: Utah | My daughter's 2078T (all black, not the Sweetwater T), has the truss rod cover on the headstock. The neck is the same all maple T neck that is on her sister's 1778T, also with the truss rod accessed at the headstock. |

The Sweet T is just a 2078T with no special designation on the sticker.
They just grabbed some 2078T's off of the line and routed in the Koa. |

Not all ANS necks have dual Truss Rods or they buried them. Bolt ons are the way to go though. |

That's why I'm plastering this one. |

I suspect alcohol is involved. |

Thanks for all the pictures guys, it makes it a lot clearer. |

It keeps the end of the Fretboard from "humping".

And all this time I was assuming the previous owner was clumsy. |

It's the cut of the grain as the heel extends. Most really pretty Maple is real close to self destruction. |

Flame Maple or any wood needs to be dried and stabalized appropriately. The curl, flame and extravagant grain can make selection difficult. It also makes it luscious
Maple and Alder may have deeper "Rays" that open up. Mahogany doesn't do that.
Its just that I have seen 5-7 heels open up like this. |

Location: NW NJ | Paravillintiniay - we kinda hijacked your thread, but PLEASE don't go rooting around trying to twist those neck bolts. OMA and Woody have told ya what can happen to the heel. IF you really have a 2078T (which several of us do, including OMA) it WILL have a truss rod cover on the center of the peghead face next to the nut. The truss rod is adjusted from there. Then all you have to know is "righty, tighty and lefty, loosey" looking from the peghead to ward the bridge. |
