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 …
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 …
This is the best full frequency range pickup! The XR Spectra v2 is now available for pre-order, with an estimated 4-6 weeks lead-time. See below for pricing info. For inquiries and orders, please send us a message using our online contact form. Overview The XR Spectra pickups are low-impedance pickups with a uniform frequency response from …
Finally, we’re shipping the first batch of XR-Spectras. The second batch is pending production, as we wait for new circuit boards to arrive. Don’t miss out on the OEM pricing. The second batch will still have the original OEM pricing as listed, following this link. For further details, have a look at the XR-Spectra User’s …
This global shortage of semiconductors is hurting us! I was hoping it will end soon, but it’s getting worse. Now, we have supply problems with ALL semiconductors in our products, and I have to redesign around the problem with alternative chips, whenever possible. Or, find alternative sources. We hit a snag last month with the …
We make simple things extra spacial. Here’s the completely redesigned Tone Block. Follow the XR-Spectra reference manual for more information (check out the Tone Block section). Available with the active XR Spectra configuration, the optional Tone Block is a small passive second-order (two-pole) resonant RLC filter with variable frequency and Q (resonance). It is specifically …
Busy! The XR-Spectra is now in production. Again, a big and special thank you to all early adopters who preordered the XR-Spectra on the first batch. If you are contemplating on ordering, now is the last chance to avail of the preorder discount (currently at OEM pricing!). See Pricing and Availability. After a rough start, …
Here’s a post about XR-Spectra’s passive mode. The XR-Spectra pickup can be configured as passive (no electronics, no batteries) by replacing the Preamp board (installed by default underneath the pickup), with the Passive board (also included).
