Re: Iron Maiden - Brave new world tone
They had a great sound around that time. Live too. Pretty easy to nail with a JMP-1 preamp.
Getting those early 80's sounds down to a T, proves much harder though. Even though it's no secret what they used (it's in the booklets and all over the net these days), how they used it and in what order the pedals were is still kind of a mystery.
