There is an article in Guitar World titled " Ritchie Blackmore: Talking Tone, Gear, Deep Purple Years and Rocking Rainbow revival dated Aril 2018. https://www.guitarworld.com/artists...ep-purple-years-and-a-rocking-rainbow-revival Interesting stuff raised by Ritchie especially about Marshall. Most of this stuff is not new at all and repeated many times and probably somewhat true. But, Ritchie is a notorious fibber, prankster and bullshit artist in interviews and has been for years. So take it for what it is worth. But, he claims before Marshall perfected his customized Marshall Major rig that they could not create his tone he loved from his (what he thought was under powered) Vox AC30. He claims that Marshall put Vox electronics in a Marshall combo and swore him to secrecy until they figured it out and added the extra gain stage he wanted in the Major. I knew he liked Vox and often recorded with Vox but I never heard the claim that he had a Marshall with Vox electronics before. A notorious odd duck, Ritchie is the only artist Ive seen that never throws a bone to his signature gear. His Custom Shop strat is $5K and he never plays one and never promotes it. Same with his Engl. He still plays Engl but not his amp. So who knows if this is true.
