I have a LÂG Tramontane T300AE which developed a belly bulge here in the Philippines where the relative humidity is normally 80-100% everyday.
I humidified the underside of the bridge first by putting a wet rag for an hour, then clamped the guitar between two pieces of wood, tightening slowly to flatten the bulge.
When the bulge flattened, I dried the guitar by putting desiccants inside, covered the sound hole with a sound hole suppressor and wrapped the body in a garbage bag.
After about 2 weeks of sucking the moisture out, I tried stringing the guitar to pitch but to my disappointment the bulge crept in again and increased the string action at the 12th fret from 1.5mm to 2.1mm in 2 days.
I asked a friend to get me a bridge doctor from StewMac and now that it is mounted, my guitar is back, action is steady at 1.6mm.
