Can anyone confirm that the abraxas neck is actually hotter than the emerald neck (noticably so).
One the bridge PUs, to put it in perspective, the RY is sometimes cited as being a less hot nailbomb, with a tad more vintage feel in there. It has little less but about equally tight bottom end and therefore emphasises the high mid agression more / in a different way. Also it is slightly less compressed / more open.
The HD in comparison has a more musically rounded top end neither the NB nor the RY exibit, generally being more musically saturated without loosing cut. Just a less agressive in the mids and a tad fuller there.
Also the on the count of the RY, which I cannot praise enough, it is a more versatile PU than the Nailbomb, which is the narrowest of the 3 in mind. As it reacts incredigly sensitive to height changes it should be able to be tweaked into a nice stoner sound.
All three will work in the end, just in different ways.
