Strange thing. I picked up a 6120-55 not long ago. Posted a NGD thread about it. Anyway, that's not the strange thing, because it's AWESOME. The strange thing is that I put an aluminum Compton on it and my high E was suddenly muffled/dead sounding. I just had a chance to pop the compensated aluminum bridge back on, and it's much better. I have Comptons on all my other Gretsches and have put them on countless others that have come and gone and never experienced anything like this? It doesn't sitar, and I know it's not the nut because it's the same whether fretted or not. Anybody ever had this happen?
