NN Sub Octave Bass

NN SOB 1.01.png


For over a decade I had been searching for an instrument that would allow me to tune a full octave below a standard four string bass without losing definition, volume, and sustain. After failed attempts with all of the prime candidates, Lignum and I came together to create the ultimate sub octave bass.


We knew it would need a massive scale length, a reinforced neck, and specialized electronics. Lignum has a degree in Civil Engineering and specializes in wood (Lignum is Latin for "Wood"). He determined that a scale of 42" was necessary for the low E (E0), and could then multi-scale down to 39" for the G (G1). Paired with my Bartolini prototype NN pickups, and an HR-4.6AP/918 active preamp with the bass control centered at 30Hz, we were off to a good start.

There was one important aspect that still needed to be addressed... the playability. A conventional approach to the 42" scale would have been a mistake. The lower register needed to be brought in, closer to the fretting-hand shoulder, and any weight from the instrument's neck and headstock that could be shifted towards the body would benefit the instrument's balance. This was achieved by elongating the body with a tailpiece, allowing the bridge hardware to be placed back 5", achieving the more common 37" scale feel. From there, we delved into aesthetics and watched the instrument take shape. 

The first sub octave bass was delivered to me at the Ziggo Dome in Amsterdam while I was on tour with Porcupine Tree. Hearing the E0 loud and clear without an amp was surprising and impressive. It was mesmerizing to feel the bass's strong resonance in my hands and torso. The neck has a reinforced design including a custom hand-made truss rod, and the strings are very heavy - about four times the weight of standard bass strings. My mind was completely blown when I played the instrument through the system at the Ziggo Dome. Oh my word. How rewarding a project. I had to share it with my fellow bass players. 

The first video I made for my YouTube channel after getting home from the tour was a demo of the sub octave bass. The response was encouraging; I didn't realize so many other bassists were searching for the same thing I was. Lignum and I didn't expected much more to come from our collaboration, but thanks to the outstanding number of purchase requests, we decided to make the instrument available to everyone; now with further refinements (thicker strings, wooden knobs, 1mm thickness added at the base of the neck, new pickup options, etc). I am extremely grateful for this opportunity, and I can't wait to hear the music that comes from other players with their NN Sub Octave Basses. 


While I suggest sticking with the foundational design aspects of the sub octave bass, every single instrument is CUSTOMIZABLE. If there is something you would like to change, such as hardware, electronics, wood, etc, Lignum is happy to accommodate.
