I have been playing and tweaking guitars for over 30y myself, so I'm fairly sure I know what I'm doing :) Woods are not the issue, I have several mahogany axes basically similar to this and they have more then enough high end. They all have floyds and thus enough steel to give them the edge I'm looking for. Maple adds lower highs, but mellows those harsh high-highs, which would be the opposite of what I want.
I don't want to sell it, I love the tone and feel, this is just about slight fine-tuning to make it 100 percent perfect.
For now I think I'll try the Wilkinson all-steel PRS-type trem, it's a straight swap so I'll be able to see the result rather quickly, while keeping the original trem as-is. Just ordered one.
Thanks for your Input everyone
I'll let you know the results
