Ssomewhere, to my ear ( and perhaps my head ?) , there is significantly less attenuation In the vicinity of 2.5k when one hits the WalnutPoper then hits another component of a kit. To my ear, it sounds as if a comb filter has been applied to reduce at 2.5 K to only the snare. The rest of the kit seemingly bypasses this reduction @ 2.5k setting

So an obvious solution is to boost the snare EQ by a couple of dB @ 2.5k if one’s ear benefits , or suffers the same ailment as mine. Lol.
