rwinking Posted April 15, 2022 Share Posted April 15, 2022 In another thread I spoke about getting the blue JTV-59US, but this is a different question. I really like the sound of the P-90s but I cannot handle the buzz. I am considering replacing the P 90s. Dimarzio is giving me a set of the Fantoms to try. I can't do the swap, but is it just a normal pickup swap for a guitar tech? Quote Link to comment Share on other sites More sharing options...
psarkissian Posted April 15, 2022 Share Posted April 15, 2022 1) Have to use pick-ups with a DC resistance (DCR) spec of between 6k Ohms and 8k Ohms. It needs to be matched to the active circuitry or the EQ tone won't sound right. 2) Follow the wiring diagram for 59's that is in the Knowledge Base here. 3) Chances are the buzz is from the set-up, it probably needs to be dialed-in just a smidgen.

rwinking Posted April 19, 2022 Author Share Posted April 19, 2022 So I checked with the dimarzio folks about using the Fantoms and he had this question about being higher than 6k-8k 0hms The Fantom is higher, however, I’m not sure why they would speck a DC resistance. Aren’t they using the output for conversion to all the synth sounds? Quote Link to comment Share on other sites More sharing options...
rwinking Posted April 19, 2022 Author Share Posted April 19, 2022 I also looked at mini humbuckers from Dimarzio. Would they fit? The neck was at 6.11kohm but the bridge was 8.25kohm. Would that .25 extra mess with the sound? Quote Link to comment Share on other sites More sharing options...
psarkissian Posted April 19, 2022 Share Posted April 19, 2022 Not by much. You may not even notice. It becomes more apparent as you go higher. 10k is darker, 12k is darker almost muddy. Would be easier to use Workbench HD. That way changing it is easier than physically messing with it. Quote Link to comment Share on other sites More sharing options...
rwinking Posted April 19, 2022 Author Share Posted April 19, 2022 Not sure what you mean by using workbench. I use it on the models for sure. My complaint is why do I need a pair of noisy P90s when the models of the P90 guitars are pretty close. It would be nice for me to be able to use the magnetics without the hum and some mini's or quiet hum cancelling P90s would probably make the guitar a better fit for me if I can find a way to do it....

psarkissian Posted April 20, 2022 Share Posted April 20, 2022 Looking over their specs, like other pick-up makers,... it's assumed it's going into a normal guitar with passive electronics. Variax system is active electronics, and requires passive pick-ups to have a certain DCR range or it won't match to the rest of the circuit, an that will change the tone EQ. As for noise,... one also has to consider the sources, such as lights or nearby appliances. I have a Gibson with stock p90's, never had a problem. Serviced JTV-59P's (with P90's), noise is only a problem when I face florescent lighting here. Quote Link to comment Share on other sites More sharing options...
rwinking Posted June 4, 2022 Author Share Posted June 4, 2022 Noise is always an issue for me whether it is a strat, tele, or P90 pup. I have guitars with single coils and love them but in certain venues they can be ridiculous. My guitars are all properly shielded and all. I am ok as long as I am turned just right. Even in a well wired studio it will be there, but again, sitting just right is the key.Has anyone put a mini humbucker in one of these JTV 59s with the P90s? According to psarkassian the DCR range on a couple of the Dimarzio minis will work. Will I need some kind of adaptive pickup ring or something to make them fit? rick Quote Link to comment Share on other sites More sharing options...
