Bridge pickup, grindy overdrive, like the Tech 21 Oxford or other Orange amp based drive, blended with clean signal, via for example of Boss LS-2, really thin pick, like thinner than you think, try the .50mm Dunlop Tortex, has to be realtively hard material, no Nylon pick, or cut your nails to a very specific length, ver inportant that they are neihter too short or too long, too long and you get a click instead of clank, and too short and you get thud instead of clank, just so that when you hit the strings, lightly!, no extreme force or you get a thud instaed of clank, in a slight inward slapping motion, with the absolute tip of your fingers it touched the edge of your nails too.
And also relatively thin gauge strings helps too.
Staninless steel, hex core, strings too.
Not too low action or you will get buzz instead of clank!
That's what I do.
Ah, and also boost some narrow spectrum around 800-1.2kHz or so, mids in general is your freind, espcially upper mids spectrum!
For growl, snap and clank!
