The mash up this time is the NT Harbinger Fuzz (Op-Amp Big Muff style fuzz) and the NT Kicker. The Harbinger is loud, gritty, in-your-face, kind of circuit. The NT Kicker (Klon Centaur) well it is just about as transparent boost that you could ever want. I don’t think that there is any pedal you couldn’t add the NT Kicker to that the circuit wouldn’t benefit from. Totally satisfied!!
