Hotly Wound Single Coils & G string Twanginess

    I sold my Carvin J99a pickups to a friend to purchase the "beefier" Carvin JVA (Jazz Vintage Alnico) pickups. "Vintage" might be a misnomer given their 8.69ohms rating--mine are actually 8.72 (The 62 Fenders are 7.5 ohms)

    Frankly I am not sure to what extent the JVAs differ from the J99As regarding the sonic "Fatness of my G & C strings--i simply can't remember! I kinda miss the scooped sound, but can't remember how the high string sound stacked up comparatively.) 45 to 25 gauge strings differ from larger gauge in thst they have only a single outer winding over the core & they always sound light! (No .050 for me either).

    Does the additional midrange thst comes with 8.72 ohms tend to translate into boominess & mud (like a split coil) or nasal twanginess? I have fooled around with cutting @ 400-500hz (presumably the source of a nasal quality, & the G & C strings get leaner not fatter--but these "dial it in experiments can mislead.

    I can get those J99As back, & my decision will be based on which will make my high strings sound fatter. So I am hoping to get some insight from TB users who have lots of experience with pickups & perhaps wind their own

    Incidentally a long interval elapsed when trying out the new JVAs because I fried my 500k blend pot installing them. Carvin still hasn't updated their FR comparison charts

    There are lots of reasons a G string twangs. Somewhere I have an entire thread on it, which I can't find this morning (haven't had the second cup of coffee). If you can find it, it should answer some of your questions.

    Principally both the G & C strings are constructed differently. I am quite aware that going up from .040 to
    045, & going up from .025 to .030 cam give you a stronger fundamental & a fatter sound, however the caveat is, that the string is stretched more tightly & can produce more overtones thst on some instances can make the string perceived as brighter. However my strings of choice are Hibeams & the bigger gauges have the fatter sound on my gear.

    On this thread the issue is more about how an unusually hotly Wound Single Coil PU differs in frequency response. There is going to be more mid range emphasis (mid range mud scooped sound lovers might argue) & the sound will approach that of maybe a split coil. As a matter of fact Carvin made this particular 8.69ohm pickup to match the output of the split coil of their PJ bass.

    So my perception of P basses is that all things the same, a G string will sound fatter than its Jbass counterpart. Is that true. (My bass underwent several changes from the last time I heard it with the J99As to the switch to the JVAs
