Re: Tighter JB?
As the story goes, I had two Charvels and both needed new bridge pickups. One had a Gravity Storm which was WAY too bright and the other had a tone zone which could be amazing about 10% of the time and the rest of the time it was just way too fuzzy. And I have a JB in an all-maple G&L that sounds AMAZing and I wanted that tone in my other guitars. A tighter JB with the same cool mid spike and soaring highs that never got harsh.
Initially, I got a Dean Baker act, but it wouldn't fit into one of my guitars (Charvel decided to drill the pickup cavity too narrow) and the Dean pickup was too big for the cavity. So I put it in the other guitar.
I ordered a JB with the intent to modify it with different mags and shorter hex screws. The heads of the hex screws turned out to be too large in diameter to fit into the JB. Out of frustration, I ordered a Dimarzio FRED (always been interested in that one). So the FRED is on order.
As for the DMT Baker Act-
I just got it wired up and its a VERY LOUD pickup that shreds and shreds and shreds. It doesn't clean up well. It has slightly less upper mids than the JB. Not scooped sounding at all. I think its a one trick pony and it does that trick very well. More suited to metal than any other genre. Classic rock didn't work well. Bass is tight. Its got soaring high end. It might have a tick too much hair on the highs. It overpowers the neck pickup, a Dimarzio Area 67'. Single note runs were a breeze and there's enough bass response that a neck pickup really isn't needed. I'll have more comments when I've played it more. These are my initial impressions after 30 mins of playing.
