Most likely this, would be my guess.Are you 100 percent certain the electronic circuits are identical in both guitars? Even relatively small differences in, say, the resistances of the pots could be enough to make a difference. But could be something as straightforward as 1M vs. 500K pots, etc.
Have you measured the resistance of the pups and pots? Fwiw,I put those exact pups in a Lp special knockoff and am quite impressed. The neck is really nice. The bridge is a little nasally, but still an upgrade from what was in there before. Not bad for a $35 set.Okay, I understand there will be some tonal differences. One of the guitars is a Les Paul copy, and the other is a 335-ish Ibanez AS-73. The Les Paul copy is more aggressive sounding and the Ibanez sounds a bit darker, which I get. But the Ibanez also seems to have lower output when hitting the front end of the amp. More preamp overdrive from the Les Paul copy. Theoretically, could different guitar materials/construction/type actually affect signal amplitude when leaving the guitar?
One theory I have is that since the high-end seems to be tamed a bit on the Ibanez, that's less signal overall hitting the amp. I don't know. Is this how it works?
Pickup set in both guitars is the Guitar Madness '57 Alnico II Special.
I'd argue that in your instance, probably what's causing the differences might mainly have to do with:I love TV Jones Filtertron style pickups. I have a hollow body Gretsch and a partscaster Tele/Cabronita with the same TV Jones pickups, and the neck pickups sound worlds apart. The Tele is brighter and more compressed sounding. The hollow body is more midrangey and “looser” sounding. It verges on jazz guitar tones. The partscaster solidbody never gets close.
the construction and materials of the bodies make a big difference.
Yeah, that's the thing - in my Les Paul copy, they sound great (to my ears). In the Ibanez 335 copy they sound great too but the output difference is what's confusing me.Have you measured the resistance of the pups and pots?
