the only thing that make me don't like a2 pick ups is the lack of bass at bridge..
played burstbucker (all type) but like them only at neck..too thin for me at bridge.
what do you think of 57 plus and seth lover bridge about their bass responce?
For example i've a vintage epiphone G400 with a seth of 59...and 50's wiring... and a gotoh heavy bridge.
what i like a lot is the balance between neck and bridge...ok...bridge is more brilliant..but has a lot of bass...
In the gibson sg with 57 classic for example (but also with 490R - 490T) you hear that the bridge is lacking some bass...
For sure...alnico 5 or 2 that pick up is unpotted...and this is one of that things that make "that sound".
Uncovered sounds more open and airy...covered but potted sounds a little bit costricted and unidimensional...
infact except the covered pick up that come on my yamaha sg3000 (spinex pick ups..something exceptional) and the always covered that come on my Yamaha sa2200 (335 much better copy) i find covered pick ups to be very straight..mono...for lacks of better words...
