Acoustic guitar
Pulls a clean, full-range signal from a piezo pickup without the harsh quack a passive box can leave behind.
Active direct box · 48V phantom powered
$220 USD
The active DI that ended the battery argument. Phantom-powered, with the headroom to take a hot keyboard or an aggressive bass without flinching — and the build to do it for a decade of one-nighters.
A direct box has one job: turn a high-impedance instrument signal into a balanced feed the console can trust, and add nothing of its own. The J48 does that with a discrete Class-A circuit and enough power reserve that transients stay intact. The result is a track that sounds like the instrument, not like the box.
On the rider
Every connector is panel-mounted and reinforced. The switches sit recessed inside the book-end so a dropped road case lands on steel, not on a toggle. Engineers spec it because it comes home from the road measuring exactly the way it left.
Headroom to spare
Active keyboards and modern basses put out signal levels that overwhelm a passive DI. The J48's power rail gives it the headroom to take the hottest source on the stage and pass it clean, so the punch you played is the punch the console hears.
Applications
Pulls a clean, full-range signal from a piezo pickup without the harsh quack a passive box can leave behind.
The merge switch sums left and right to mono when you only have one channel, with no level penalty.
Handles a hot active bass without padding it down, and a vintage passive without losing the low end.

“I carry two J48s in every kit. In fifteen years of touring I have never had one fail, and I've never had one color the sound. That's the whole job, done.”
