I have both guitars a brw neck 513 and a maple neck/board Brent Mason. They are both very much their own thing, my 513 has been modded with a push push tone to add the bridge pickup to any others selected by the 5 way, I will do a similar mod to the BM next timeI change the strings. The 513 has a darker tone than the BM probably due to the different timbers and it is much heavier, with the amp set correctly it can give a huge range of tones single coil mode is like a very powerful strat more SRV than H M ;-) I t can get more stratty if you lower the pickup (being an early one mine ar pcb mounted so you have to be careful when adjusting heights not to cause bad joints). There is a noticable volume difference between the single coil and hb modes on the 513 muchmuch less so on the BM. The BM is much more Fender like in terms of feel but wind it in hb mode and it can do a fair impression of a Lester, the slippery neck was one of my main reasons for getting the BM after enjoying my NF3s easy playing. Overall the 513 is probably more versatile but the BM has got to more gigs recently mainly due to is weight and hss options, 513 is either sss or hsh (2 modes) where as the BM can do sss,hss,hsh or ssh guess it all comes down to which feels best in 'your" hands in the end ;-)
