I think that both the Emerald and RY should lend themselfs rather nicely, with the emerald being my main pick.
This is mostly based on what should work well with 8 strings. Factor in 80s heavy metal and you get those two for me.
The Emeralds brightness and tighness should work very nicely with 8 strings, after all it is one of the most recommended there for extended range instruments. Also the voicing can work nicely for heavy metal but can go very modern too if wanted.
Somewhat the same with the RY.
So you suggesting Rebel yell for bridge and Emerald for neck if I figure it right?
Manni Schmidt used EMG81s during his time with Grave Digger. He used different amps and at one time was an endorsee for the Fame Bulldozer - a Mesa Rectifier clone. At some point he used a Laney, at another an Earforce amp. I guess he liked to switch things up.
He used a Boss Pedal as boost most of the time - can't remember which one, it was not the SD-1 but a "higher powered one". Turbo Distortion maybe...?
Personally I loved his sound. His wah lead sound on "The Grave Digger" album is awesome:

From BKP, well I think the Miracle Man would be the best bet for a fat sounding mahogany guitar. It should work best for most styles.
Well me personally love Grave Digger too, Excalibur is my favorite album from them:

So Miracle Man would do the job for 8 string guitar? For bridge and the neck also?
I think this guitar has the same would as mine Hellraiser 7 Fr . Mahogany body with quilted maple top, mahogany neck with rosewood fretboard.
Thanks for all your comments so far. Much appreciated.
