I have played guitar for 21 years, and Iron Maiden was the reason I started. If Murray or Smitty were to leave, I could honestly jump right in and play their complete set to a T. When I was much younger, "Live After Death" was my practice routine. I can play about 80% of their songs note for note. My advice to anyone wanting to learn Iron Maiden songs: LEARN THE Em penatonic scale! You can then play a large amount of their solos.
My guitars: Gibson Les Paul Standard, Gibson Les Paul Custom, Gibson Explorer, Fender American Strat, Black Squier Strat (tricked out just like Murray's guitar-my first one), Jackson Dinky, Carvin Flying V, Guild D-30 acoustic.
Rock On!
