I actually measured mine with calipers, had to get the internet to do the metric conversion for me
The four i have ranged from 0.309 to 0.311, I agree it sounds like what you've been looking for are the same as what I have.
I'll see if I can fit the module in this bass's electronics bay, if so, once you get the new pots, I'll see how it sounds with an '87 Ibanez
I noticed on your ebay listing you have the L & W dimensions for the PCB listed, do you also have an H measurement for the -01/solder version? So I can check all three dimensions for fitment....
Thanks for the info, btw!
....oh, I meant to ask - how are the splines on the shaft counted, considering the split? If my original knobs will fit, that would be awesome

I did my own search and found these:
ALPHA POTENTIOMETER B100K 100K 16MM LONG SHAFT WITH CENTER DETENT CLICK GUITAR BASS
If you don’t use a locking wash, they do just fine in the current Euros. They have a 6mm split shaft. Euro knobs do fit. Early Euro knobs (maybe 2000ish) were slightly different probably required a 1/4“ split shaft.

PS. A slightly longer thread would be still better as the Spector push-on knob is pretty deep, 18mm and will sit only partially on the axis.
EMG pots have a good length. man, Spector finishes are pretty thick

The PCB is 14mm (0.552" with my antique road worn calipers) from bottom of the board to the highest point, which are the 3 large caps. I'm also attaching a couple photos showing how it fits in my 2008 Spector Rebop, and the height comparison of the 18mm pots (Bass and Treble pots I am having built) vs 20mm pots (Volume and Blend) from EMG using the original knobs.
Note: This Spector is a bit beat up. I just bought it a couple months ago from guy in a metal band who hated and was looking to trade it for something flashier. She needs some cosmetic TLC, but sounds amazing.

Yes, it would be very easy to do! I'd just grab an enclosure from a supplier that also does powder coating like stompboxparts.com (probably go with a 125B size), get it pre-drilled with 3 pot holes (Bass, Treble, Volume) a hard-bypass switch, and DC input jack, powder coat it a retro hazard yellow color, and throw a cool logo on it.
I'd name it "Hazard Lamps" as a nod to the HazLabs name, and make it look like an old-fashioned warning or radiation sign, maybe distressed looking.
Inside, I'd mount the LHZ on insulated standoffs. Wire it to the pots like it was on a bass, but instead of pickups it would be wired it to the input jack, the output would go to the output jack, and power from the DC input so I didn't have to worry about switching off the battery.
I was thinking it might be fun to play with adding a straight (no coloration) boost before the LHZ as I have a feeling this might make a really interesting OD pedal for guitar as well due to the way the chip reacts when pushed.
Thanks for that!
Exactly what I needed - I think I can fit it where the battery is now, and relocate the battery to lying over the top (with its insulating wrap on), flat between the pots & cover.

Makes me wonder if I could feasibly do some sort of "loaner" program on the LHZ-02 units? Basically have a unit that potential buyers could try out for a few weeks for just the cost of shipping, to see if it fits and does what they hope it will do. Hmm...
Not a bad idea....
Really all you'd need is a bit of plastic or wood or some such, just a rectangle box, in the same size & shape? If simple enough, might not even need to be returned.....
Or do you mean something that has the topography?, I guess?, in case some components may need to sit inside the boundaries of just a straight box shape?
Maybe a reject board, with some dummy components?

What I was thinking is possibly making 1 or 2 full LHZ-02 units and just designating them as trial or loaner units. Kind of like a library book. Not sure if the preamp will fit, or gives you the sound you are looing for... just get the trial unit.
It would basically cost the shipping fee (send and return), plus a nominal charge for the non-reusable connectors. Let's say you have a month to install it and give it a good run. If it's not a good fit, back in the box to ship back.
If you want to buy it, you can either ship the loaner back and get a brand-new unit or buy the unit you have for the difference in price.
On my end, incoming units get cleaned and put back on the test rig to make sure they are still fully functional.

Do you have the 40DC as the bridge pickup? Also, what pick up do you have for the neck? Wonderful tone!
The Euro 4 was Them Bones by Alice In Chains, the other was Megadeth‘s Five Magics Intro of the „Rust in peace“ album. Glad I could help!

@Maidenfloyd: You should know that @fibz is the OG of pickups and preamps! He was one of the original 2 beta testers when the LHZ was just a hobby project here, and his extensive cataloging of sound samples every time he swapped something out was the inspiration for me to keep developing.
As soon as he posted the LHZ samples to his archive, I started getting inquiries.
That’s awesome! I know he helped me a lot with his sounds clips!

Earlier this year I acquired a 2006 Spector ReBop 5 DLX with original equipment, and saved the entire TonePump and potentiometer assembly when upgrading the electronics. Since Spector does not seem to have a schematic of how the older non-trim TonePump preamps are wired, I thought I'd create a diagram for reference and share it here.
