I've had a German made Warwick Streamer standard for... 23 years now. The pickup in this thing has always been a mystery. MEC don't sell them on their website, and I'm a curious sort. So you can buy the pickups on AliExpress... I've potentially wasted £22.99 here just to satisfy my curiosity. I'm assuming they have fallen off the back of the lorry that was delivering them to where ever the Warwick Rockbasses are made. So I bought one, solely with the intention of taking it apart to see how it is constructed, and maybe even swapping the magnets to give a different sound. I think they pickups are generally unliked... They are 500hz city... so much midrange. Personally, I do like them, but I feel I'm in a minority.
Anyway, the pickup arrived. As far as I can tell it looks genuine and measured just under 7k in series. It is a completely sealed unit, just like the one on my bass. Whatever the goop is that they sealed it up with... its softer than epoxy, harder than silicone, and softens rather readily under the heat of a hair dryer. Pictures are worth a thousand words, but in short, it looks to be constructed from two Firebird pickup bobbins...
WSC can be seen stamped on one of the bobbins. A bit of googling suggest that this might be for Woo Sung Chorus, who rebranded to "Roswell" "AB45" is also visible on the bobbin. MEC say they make all their pickups in Germany, so maybe WSC are their bobbin OEM.
So what to do now? I'm tempted to melt all the junk out and try a magnet transplant; swap them out for something alnico?
Anyway, if you've ever wondered what's in these things, or what kind of pickup it is modelled after... it umm... look like a firebird pickup!
