We don't have a direct retrofit for an Ibanez TMB 100. The closest match is the HE6C 1/2" (Ultralite Xtender)
The Ultralite Xtender is designed for an 11/16" (17.5mm) headstock hole while the TMB 100 has a 25/32" (20mm) headstock hole. This will mean that the hole needs to be plugged with a dowel and drilled out to the correct size.
