ROUGH BY DESIGN T-BASS FRETLESS PIEZO. A T-Bass (we all know what shape this is) as a Rough By Design fretless model. This is not relic-ed but, just as the title says - Rough By Design - by which, it does NOT mean that you're going to get splinters when you play it.. It has a blue wood top veneer and a piezo bridge with it's fretless'Vine Of Life' inlay.
