So I currently use the 2 stock J pickups on my 5 string Ibanez GSRM25 Mikro bass wired in series directly to the output jack socket of the bass, and for such cheap pickups they do sound surprisingly great, but as I have to run the bass through a graphic EQ boosting the 280Hz band about 4dB, the 500Hz band about 6dB, the 800Hz band about 6dB, the 1,4 Khz band about 4dB and the 2,3Khz band about 2dB, to get my tone where I want it I thought maybe there would be an alternative that would get me closer to that tone to start with. I would describe the tone as very snappy with a good amount of bite and clank, but without for that reason really lacking low end in any possible way (though not exactly a thunderous amount of it either). (Also note that it actually doesn't sound quite as the sound test I posted of it yesterday in the Recordings forum anymore, as I have changed the EQ settings since, basically just rolled the 100Hz and 170Hz bands on my graphic EQ back to zero, from being slightly boosted on that recording). Now the problem is that both the 2 pickup covers, neck and bridge, of the 5 string Mikro matches the measurements of a regular standard size 4 string J bridge pickup (as far as I can tell from my own measurements and cross checking with the listed pickup dimensions from various manufactures), except for the fact that the string spacing on the Mikro is just 16,5 mm, and that it got 5 strings. So my question is, as the headline says, if there are any mid heavy, single coil, 4 string, J, rail based, bridge pickups that possibly could give me the tone I am looking for when wired in series. I am open to suggestions, weather it be cheap budget or more regular mid to upper mid priced pickups, but it needs to be pickups that can fit in the existing pickup cavities of my bass, which means standard sized 4 string J bridge pickups, as well as they need to utilize rails instead of pole pieces, due to the 5 strings and tight string spacing, and finally they will have to work well wired in series.
