Description

Edit description

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.

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.
