Especially in an LP or 24.75 scale guitar, which are naturally boomy or muddy, the roxy feels like taking a veil off the top end and high mids, and really controlling the low end, but not sounding thin in any way
Especially for the chuggy palm muted parts in that first tune i posted
I couldn't use a guitar with a duncan custom in the bridge - it's just too smeared sounding, and you can't tell the individual notes and stops. Which is absolutely integral to the riff sounding cool in my opinion. The staccato start/stop of the riff is what gives it its "fire" and "motion"
