The PolyPaf uses the same unoriented (isotropic) Alnico v magnets as the Peacemaker, so you'll feel some similarities in how they respond - less edgy and immediate compared to the Nailbomb or Black Dog, which both use regular anisotropic Alnico v - but the coil build is very much different, more similar to a vintage P.A.F, using 42AWG enamel wire for a brighter chime and trimmed bass, plus we have worked in some different alloys in the slug poles, using a higher carbon content slug under the wound strings, which both slightly alters the string balance for a little more presence in the mix for the plain strings, but also brings out a richness in the mids.
In summary, and in answer to your question, the PolyPaf is less powerful, a little more delicate and has more bias towards the higher frequencies than either the Black Dog or the Peacemaker. It is less muscular and, as a result, more open and chimey.
