I just ordered the GOC Ilumina B37.5 - Jager bass. I haven't seen much talk of them in the forums, so I figured it would be good to start this "club" thread.

Why did you originally want to replace the pickups?....originally wanted to put in...
When i found out about the bass first thing that came to my mind to make dingwall like bass nr2 (i already have redsub colliseum 5) with dingwall pickupsWhy did you originally want to replace the pickups?

Micarta (Quartersawn Wenge Simulation)
An eco-friendly alternative material made from 100% natural ingredients without plastic or other petroleum derivatives. It has been developed for several decades with the sole purpose of creating the ultimate wood product meant for musical instruments replacing the usage of exotic and endangered species.
Its main ingredient, the European Pinus Radiata, is known to be one of the fastest-growing and easily harvested. With dozens of patented processes, the wood fibers change texture, density, and hardness, creating a superior wood product to its natural counterparts.
This engineered wood fiber is systematically made upon consistent hundreds of layers simulating a quartersawn wood for added strength while still being flexible. The grain of this material is dark brown and may have some natural pits like you would see in a raw wenge wood while being smooth and fast.
This has been the critical element that drives GOC Guitars in its mission to push eco-friendly guitars using green sustainable products. Micarta has different levels and grades depending on usage.
Fretboard: Richlite
Richlite, founded in 1943 and located in Tacoma, Washington, manufactures and sells a durable surface material composed of resin-infused paper. The material, comprising roughly 65% FSC-certified or recycled paper and 35% phenolic resin, was originally used in industrial tooling. Its versatility and water resistance have led to applications in countertops, skateparks, and cabinetry. Architects and designers value its appearance. The company highlights its sustainability measures. Richlite products are generally comparable in price and upkeep to quartz.
By chance did you order after the 2026 version announcement was made? I got my 2026 bass a few weeks ago and just now plugged it in, I'm having the exact same issue with the pickups. Can't have the blend knob in the middle position otherwise it's out of phase. I guess I'll have to hit up GOC for this too. I already had to hit them up about my 2025 version with major clipping issues with the preamp. Made it unrecordable. They sent me the new 2026 electronics to have installed in my 2025 bass, and now I'm worried that those are out of phase too. :/I placed order for mine on 24th December, 4th Jan it came to my house (in Czechia)
Had ultra long scale elixirs on another bass and for whomever it may concern, they fit!
My illumina came with out of phase pickups but i talked to GOC and they will send me new set of pickups, afterwards I'll put on fresh set of elixirs and could take photos of nut/0 fret if anybody is interested in where winding ends
overall I am happy with bass, love the pickups (by themselves, cannot have both on at the same time), originally wanted to put in either Dingstrand Nordwalls (but they are from what i can find standard P and so that would mean that they will not be catching strings properly) or FD3n, but am scared to route for proprietary FD3n route and then find out that they won't fit
It might be, but i was advised to just switch white/black wire going from the pickups - the pickups are passive so it works.By chance did you order after the 2026 version announcement was made?

I got the same advice last night after I sent them my demo video. Seems an easy enough fix.It might be, but i was advised to just switch white/black wire going from the pickups - the pickups are passive so it works.
I just thought that pickups were active because in electronics cavity there were red wires also coming from the route from pickups.
Most pickups are passive, as far as I know. These basses have an active preamp.
This Reddit thread is about finding basses that have active pickups:

The strings it comes with are excellent. D'addario has multi scale sets. Dingwall tooI will be tuning this bass to A Standard (A0 - D1 - G1 - C2 - F2). I was worried about where to get the strings. I've been using D'Addario's nickel singles, but their wind length is just a hair too short for the 37" scale low string. While searching for string makers who offer strings this long, I discovered Payson bass strings. They have a packaged set for my exact needs! I've also ordered their 35" multiscale set for B Standard tuning to go on my Ibanez EHB 1505 MS.
Has anyone else had good luck with their strings?
They are, actually. I asked what they were, and they said they were "Pitchlab strings, but are not available to buy yet".The strings it comes with are excellent. D'addario has multi scale sets. Dingwall too
