Earlier this year I got my hands on a vintage Fodera Emperor Deluxe (JJ) from 1988. I had been searching for another one after foolishly letting go a very similar example from 1989 (PJ) that I found in Nashville during college. According to Fodera, the 1988 example shipped with Bartolinis and a HAZ Labs preamp but when I received it, it had some very old EMGs in it, so the Barts must not've lasted very long.
For months I tried to see all the good things in that combination but it just wasn't doing it for me. The EMGs have a very particular sound across all frequencies as does the HAZ Labs pre. This of course is a classic combination in Spectors for rock music, with the 2-band EQ boosted. But I typically run pretty flat. It also sounded pretty horrible when panning to either pickup. So I started thinking about replacing the electronics and the first thing that came to mind were Aeros.
I have tried some of the Aero humbuckers in Foderas over the years, but never the single coil JB4s. I got on the phone with Larry a few weeks ago and had a nice long discussion about a great many things. We chatted about preamps and how they are often superfluous. I agreed. I get spectacular tone out of my Fender Jazz with Fralins and just volume-volume, no tone control (though I've left it intact so I can put it back in the circuit if I wish). So I decided to go with the JB4 Type 1s and do volume-volume, no tone, and use the roll off on the amp like I already do. That bass has an early Fodera bridge with no lateral string adjustment, just cut brass, so Larry had to take measurements and custom space the polepieces for this bass. It's slightly narrower than the standard Fender spacing. Gotta love that!
Larry suggested a 22pF ceramic disc capacitor. I wired one up to a linear pot just in case I ever want to add in the tone control. While I was waiting for them to be custom made I dropped in some standard Fralin pickups and that was already a big improvement. I was really excited to see the differences between the Fralins and the Aeros. I've used Fralins in a lot of my Fenders over the years so I am very familiar with their sound and response.
The Aeros arrived earlier than Larry estimated. I installed them a few days ago and I couldn't be happier with the results. Everything that's been said about them seems to track with what I hear and feel. Compared to the Fralins, there is the sensation of a wider frequency response overall. Surprisingly clear but not harsh. Very good output, especially without a tone pot in the mix. There's a really nice texture in the bass and midrange that I've been going for with my technique that comes out even more now with this setup. Think Steve Swallow but without a pick. It has more detail in the highs which is what I was going for as well. This is my modern Jazz bass that I'll use with my Brazilian/latin/jazz groups and the Fralins are a perfect fit for my Fender CS 1960 RI that I use on my folk/rock/country/reggae gigs.
