May 2021: COVID-19 Coronavirus Status

I am still building and shipping during the COVID-19 outbreak. I remain healthy and am following all California state and Santa Clara county mandatory health orders. Fortunately my shop is at home, I work alone, and I’m well stocked on parts so it’s nearly business as usual over here.

Feel free to email me with any specific questions or concerns. Please keep yourself safe. I also urge you to find someone who is worse off than you are and lend them some support during this time. We’re all in this together, and together we will make it through. The real world is people. Love one another.

Noble Logo T Shirt - Camo

Traditional crew neck cut features a tear-away label behind the neck. 60% combed ringspun cotton, 40% polyester.


Pelican Hard Case with Foam Insert

Pelican Storm iM2050 hard case with laser engraved Noble badge and precision milled foam insert (insert can also be purchased separately if you already have a hard case, email for details). The Pelican Storm iM2050 is watertight, dustproof and guaranteed for life. Measures 11 1/2" x 9 1/2" x 4 1/2" with the handle folded down. Weighs 3 lbs empty, 6 lbs with preamp (1.4kg empty, 2.7kg with preamp). Both the case and foam are designed and manufactured in USA.


Spare Tube Set

Set of two JJ ECC82, individually hand tested for low noise and microphonics. These are the default tubes used in the Noble Preamp DI. JJ tubes are built rugged and survive well on tour. They consistently have the lowest noise floor and microphonic noise of all brands tested. Here's a video showing how to change the tubes.


18V DC Boost Cable

This cable allows 18V effects to be powered from a center-negative 9V or 12V DC power supply. The end with the red label "18V" goes to your pedal and will output regulated 18V when the other end is plugged into 9V or 12V DC. The cable has the same ends as a typical DC cable (5.5mm x 2.1mm, both tip-negative) but with a small circuit board in the middle where the voltage boosting takes place. The current required is roughly double; for example 100mA at 18V requires roughly 200mA at 9V. Total length is 21.5" (0.55m). The 18V boost cable carries a 1 year warranty against defects.
