Location: Brighty in Blighty | Was reading a recent forum post about a guitar that had suffered from bridge lift.
Started me wondering...
If I look closely on both my 84C and 868 it appears that there is a SLIGHT raised 'hump' on the sound board behind the bridge. So...
1. Is this natural / normal?
2. Should I worry (more than I ought to)?
3. How can one prevent it (short of detuning after each session)?
4. Bearing in mind I play in tunings (i.e. Open E) that put more tension on the neck than regular tuning am I more likely to suffer from stink foot, oops sorry I mean bridge lift?
I use 11 - 50 gauge strings so perhaps the 'damage' was done ny previous owners. |

Location: Scotland | more than a small amount of hump in the top means that standard adustments, such as bridge saddle height reduction will eventually, depending on neck-pitch, no longer fix a high action. Little or no top bulge generally means the guitar is over-braced and wont sound great. Too much top bulge generally indicates structural problems. Too little/too much/just right is a variable depending on the particular age, condition, geometry, storage conditions, maintainance, player perception, action and feel preference of each guitar. If the Bridge glue-seam is failing that is not normal and is a separate issue which should be fixed, even if it happens on a bridge that is bolted and glued |

| so there's a difference between a "good hump" and a "bad hump" ? |

BTW, We're taking wood tops here. Carbon fibre tops tend to stay pretty much as they were built. |
