I'm well aware the Collings build quality is in another league and I'm aware of the maple top being on the R-6. I'm also aware that the Lollar P-90's are probably better. I'm also painfully aware of Gibsons hit or miss set up however suppose you compared an excellent R- 6 vs the 290? What would the difference in sound be? Not sure what the maple top brings to the sonic experience? I love bottom end slam factor on power chords running through a Tweed furnace giving up the goods as well as inner detail clarity.
