The Aluminum bridge on my Rat Rod was more subtle. Seemed like it took a couple days to really settle in and make the tone better. The RR sounds really good now and I enjoy playing it a lot. After the Stainless bridge upgrade the improvement was instant and very noticeable. This guitar sounds really good. Sustains so much more than the stock bridge. $80 well spent. Going to put my G6XXX plans on hold for now.
