I have lately listened a lot to Black Label Society's "Order of the Black". I've always been a fan of Zakk's playing, but for the first time I am amazed at the rhythm guitar sound on one of his albums.
I have somewhat similar gear already and get sounds similar to his. After giving this a lot of thought I've come to the conclusion, that the speakers he uses play a large role in that big, clear and clean open end. In other words, not the amp, not the guitar and not the pickups.
Zakk uses Electro Voice Black Label Speakers, which cost way too much for an amateur musician such as I am.
There are options: The Electro Voice EVM12L, which I cannot get specs on and which still costs a lot, and there are different Eminence speakers.
People say there is an alternative, the Eminence Delta Pro 12, which is really a PA speaker. Also there is the Eminence Commonwealth, which is modelled more on something called JBL speaker (no idea)?
Can anyone give some more insight to this and maybe share experience with speakers which not only handle low bass notes very well, but do so very clear. Most guitar speakers seem to be no use below something like 80Hz and this is where the EV and those Eminence seem to excel; being not strictly just aimed at a guitar market, their frequency range goes lower apparently.
