For blues, Tim recommended the excellent 'Stormy Mondays' for a thinner bodied or hollow guitar. I moved a set from my Les Paul to my S.G. and they sounded even better/more open in the S.G.
I must admit however, that they will most probably be much too sweet and clean for your heavier influences. Blues: yes, Zeppelin: yes; - but Sabbath and beyond - no way.
Just wanted to say that the S.G. is a very versatile model. It is so often assumed that S.G. = Metal. With SMs ( or MQs ?) fitted it can do Jazz and blues very, very well.
I am sure that at some point, forum member 'Twinfan' will recommend the hotter and spikier Riff-Raffs.
Oh well, back to the inevitable 'Nailbomb' recomendations.
:D
Regards to all,
Derek.
