Amp: crunch

Volume & gain: 50%

Bass: 60

Mid: 60

Treble:40

 

(Although you could probably just do 50% on all of them, because the important part is . . .)

 

Booster: green more clean boost, or orange for treble booster.  And you'll have to dial it up or down to taste.  If your guitar pickups are hotter, then you don't need much boost (30-40%), but if you have relatively low output pickups then a bit more (50-60%).  But the boost is an important element.

 

Blackmore's tone has less distortion than you might think at first, it's a pretty clean tone, but with some bite.  To get that combo he typically used Strats sometimes with low output single coils, later with hotter single coils, then into a treble booster (an earlier lo-fi version of an overdrive) and later a tape deck for a clean boost, then into a dimed Marshall or Vox.  So, it's a thick, full sound, but pretty clean with some bite.

 

Dave teaches the song here.

 

 

There are a few videos you can find with a search on Blackmore tone with a Katana.  And there are also some Katana patches people have uploaded.  But I think most of them use way too much gain or distortion.
