Noble Dual Vacuum Tube Preamp / DI

Bass guitar sounds best through tubes, especially when running direct! Tubes distort gradually with low-order harmonics, which are perfect musical intervals. The second harmonic is an octave, the third harmonic is a fifth above the octave, the fourth harmonic is a second octave, etc. This is the reason tubes sound so good, and you will notice it. Their subtle distortion provides the natural harmonics lacking in electronic instruments, and restores the dimension and feel of your bass as it was intended to be heard.

Designed for your pedalboard

Measuring just 7 1/2” x 5” and weighing less than 3 pounds, the Noble preamp DI will change the way you think about vacuum tube gear. To keep weight to a minimum the preamp is housed in a precision machined aluminum enclosure, which is three times lighter than steel. Aluminum also delivers 30X better electrical shielding, providing a super quiet low noise backdrop for studio recording or pristine live sound. And the Noble preamp DI includes six 2ft (0.6m) DC cables to power your tuner, compressor, octave, fuzz, or other pedals from the onboard filtered and regulated 9V DC supply.

Take your studio on the road

Get that big console sound wherever you are. A great pair of tubes adds harmonic fatness and musical overtones that digital or solid-state gear just can’t emulate. The Noble preamp DI turns your laptop and portable recording interface into a tube-driven channel strip with a super low noise floor and an unbeatable vintage sound. And the ultra high 10MegΩ input impedance won’t load down piezo pickups, so it’s great on acoustic instruments as well.

Just enough knobs

When you’re using in-ear monitors you don’t want a regular old DI. You want one with knobs, but not too many. Our classic 2.5 band EQ was designed by musicians and is loved by engineers for how well it sits in the mix. The intuitive bass and treble controls quickly brighten or fatten your sound for high end clarity or low end thump. The low cut switch rolls off -6dB per octave below 90Hz to add more punch and girth in the low mids and leave room in the mix for the kick drum. And since the EQ affects both 1/4” and XLR outputs, the entire venue gets to hear your bass the way you want it to sound.
