i know a girl that has an all maple washburn guitar
cheap model (chicago series, i think), but nice guitar (except the hardware)
very bright
don't know if miracle man can be compared to JB and screamin demon cause MM has a lot more output and bass, but probably it has tons of high mids, so i would say it's a really heavy and tight pickup, but it has a bright nature too (as most ceramic pickups)
i'm not saying it's gonna suck
most people love brighter tones, but if you're looking for a low mid tone, i wouldn't go with it, not for an all maple guitar
i'll order a miracle man set this week, but for a mahogany les paul with imbuya top
if it was maple or even alder, i'd probably go with warpig
painkiller will give all the tightness and bass that you're looking for too, but it seems to have a bright nature too
