Me too and no problems either. The TT bashplate is built like a box though, with jointed, folded corners so is more rigid than OTR item. Looking at the OTR design it is the "wings" that'll be what's resonating I'd guess, as the only rigidity is supplied by the slight curvature and the thickness of the aluminium. The mounting points are a long way inboard too which probably doesn't help either.
