I'd say it sounds more like a PAF'ed up holy diver than like a hot rodded mule
it sounds nothing like the mule, in my experience
the mule has a very open and smoothly dosed midrange, while the dog has a really dense wall of mids and a "grungier" texture, almost like there's a wah or overdrive pedal
the dog sounds more reminiscent of the dimarzio lineage than from actual vintage PAFs
I'd even say the VHII sounds way closer to what I'd expect from an overwound mule, despite of its much stiffer response
I wonder if a VHII would sound good with A4
