We conducted a drop test to determine the durability of the XR-Spectra pickup. The pickup is dropped twice onto hard tiles at a height of one meter (video below). After being dropped, the pickup should continue to function normally with no degradation in sound quality.
White XR Spectra Pickups, anyone? These are white XR Spectra 82mm pickups that are currently custom ordered. I’m thinking we can make this a standard if there is enough interest.
It took us a long time, but I’m finally happy to announce that we are now manufacturing a fresh batch of XR Spectras. The XR Spectras are now available for pre-order, with an estimated 2-4 weeks lead-time. The current version is still v2, but I am changing the naming from inch to mm, and so …
If I were to re-learn the guitar, I’d learn touch guitar. I learned the keyboard before the guitar, and it just makes sense. The two-handed tapping technique was first introduced by one of the earliest pioneers, Jimmie Webster in his 1952 method book “The Touch System for Electric and Amplified Spanish Guitar”. I first came …
https://drive.google.com/uc?export=view&id=1zBXlicaqDD4ef4eHy2kbLra59SKLW-zpThis batch took a long time to finish. Logistics were a mess, plagued by delays. Apart from that, I have to admit that we had to contend with production issues. V2 was a big departure from v1, and we had to revisit our production process. But as the saying goes, better late than never. It’s …
Previously, I posted some pictures of the modular XR-Spectra coil. Two of those coils are held in place by a base printed circuit board (PCB) at the bottom. The two coils are connected, series opposing, for a humbucking configuration. The outputs are sent to a 4-pin, 2mm header connector at the bottom, with pins for …
The Lo-Z XR-Spectra coil: 1000 Turns 250Ω DCR (for 3.3″ version) 76mH AWG38 self-bonding magnet wire 2mm Type 430 ferritic stainless steel rail 1mm printed circuit board bobbin with copper-pour shield. We use AWG38 self-bonding magnet wire (also known as bondable magnet wire). It has a thin layer of thermoplastic polyurethane adhesive, activated using 140~160°C …
I love designing stuff! It’s an obsession! The picture above is the Modula preamplifier I designed in 2017. I decided to go back to this form factor for the XR Spectra v2 update. The design makes sense. It is simple, modular, and reusable. It can be connected anywhere in the signal chain; right after each …
It only gets better… Available with the active XR Spectra configuration, the Tone Block is a small passive second-order (two-pole) resonant RLC filter with variable frequency and Q (resonance). It is specifically designed as a post filter for the XR Spectra pickups, giving you the freedom to change each pickup’s character on the fly. With …
There’s a lot to say about this Nu-XR-Spectra pair than its gorgeous looks. The Nu-Multi is multichannel. If you want mono, use a mono pickup. There’s a reason why we no longer make a mixer for summing the outputs to mono. The broadband noise levels (hiss) accumulates for every channel that you add. For high …
