Bartolini pickups with EMG preamp?

Sure, you can can use that BTC with
your Bartolini CBs.

I use a BTS with the Lane Poor M3.5Ws in my Hamer 12-string. The only major wiring concern going with passive pickups is in using 250K or 500K potentiometers instead of the 25K pots which are used with the active EMGs.

I've got active/passive switches on both of my active basses. IMO, the BTS/BTC circuit does alter the tone of the instrument, even when set flat. With the EMG preamp I hear some treble boost with the preamp engaged. To my ears, going passive sounds more organic and dynamic, with a more natural sounding midrange.

In contrast, compared to running passive, I find that engaging the Bartolini NTBT preamp in my Pedulla Rapture 5 tends to dampen the extended highs of the Q-Tuner pickup. IMO, the Bartolini preamp is somewhat warmer sounding than the EMG.

 

The EMG preamp/pots will work with any passive pickup (more or less).

The question is will you like the effect/output. EMG has a patent on their rail system of electro-magnetics. Most*(not all) other pickups are wire wound around some kind of magnet structure. So EMGs preamp/controls are calibrated to boost their particular pickup flow. Its a decent experiment I guess.

I agree with 12bass in that BART is warmer than EMG. I have an EMG setup in a P Bass its very edgy and crisp but keeps the low/mid presence. The Bart NTMB 15f pre in my Tobias is softer sounding. I like soft, I like edgy, I bring both with me to every gig ussually.
