I modded Lollar thunderbird pickups into a Fender Jaguar, maybe 10 years ago. They are Lollar's take, on a vintage TB pickup. Which are a lot different than the pickups in most modern Gibsons.
They are freaking fantastic. High output. Tons of tone and texture and growl. You dont have to play hard or exaggerate your technique to get the lows, the growl, the fullness, or the sweet-yet full highs.
They will push your cab more than usual. Uncommonly punchy. And its not something you can hear in a processed youtube video.
Rolling the tone off is phat as hell. And effects seem to track better than ever, with these pickups.
They aint cheap. But, they are totally worth it.
It has remained my favorite tone. I have used various Nordstrands in my other bass. I like Nordstrand a lot. But this Jaguar with Lollar TB pickups is THE tone, for me.
