It's been one year that I use the Serial Killer and Sniper brand mounted on a STHAC SL24 Custom Shop to replace the Di Marzio EVO 2.
Precise, sharp, soft, round, angry, powerful, obedient ... everything will depend on your volume and tone knobs, switch from clean to crunch, crunch of the voicing and eventually destroy a lead, they go with everything shine and presence. Harmonic solid and warm on the first eighth of a turn of Pot. / volume.
Excellent mics do everything, but against, the game of precision pinch, they leave nothing to spend any means. You can spend a m7/5- in without distortion blurs.
Excellent value for money.
And for sure on my next scratch custom shop, it will be of Crel's or anything
