I was hoping someone could help me figuring out how to wire these pickups as the Bartolini wiring schemes do not cover them. This is the last thing I need to sort to finish my build
: NOTO Scarab 6
As the title says the Barts in question are a set of XXM56C quadcoils that I bought from fellow TB member.
The intended wiring is having each pickup splittable by means of a SPDT mini switch so to get: Rear Stacked Coils – Full Quad - Front Stacked Coils
The pickups go through an Aguilar OBP3 with a frequency selector (400Hz-800Hz) and with an active-passive switch. I have installed the preamp once before so I’m positive it’s fully working, never tried the pickups though.
Now as if things were not already complicated I decided to install the switches as I did in my first prototype, that is instead of drilling an 8 mm hole and fix the switch with its nut and washer, I leave the top thicker and drill a 7 mm hole so that I actually screw-in the switches so that only the lever rises above the surface.
The effect is really cool (IMO) but of course makes things way more complicated to wire (and also a bit messy on the eyes, but we all have messy guts, haven’t we?
). So to achieve this I have to prewire all switches and after they are all in place I wire them to the pickups and the preamp.
One thing I should mention is that, since I did not have any SPDT switches, I used 2 DPDTs (on-off-on), but just one half of each (the 2 leftmost on the pic). I read that it is equivalent. Hope that this is not the issue…
Now the first issue that I encounter is that the pickups are supposed to be quadcoils but they only have 4 conductors + shield. When I check the Bartolini site (which has been recently renovated BTW), the wiring scheme associated to them mentions 6 conductors (!?)
So I assumed that the wiring scheme for Dual coils with 4 conductors will give me the desired splitting:
BTW: The wires' colors of my pups match perfectly the diagram above
Thing is that after wiring everything (took me quite a lot of time) I plugged it in and cha-cha-cha-chaaan- NADA
So at this point I’m thinking that the pickup wiring is wrong but I don’t know how to troubleshoot it in a way that I don’t have to unwire the whole thing.
I would be really grateful if someone can point me in the right direction. If pictures of the actual wiring are helpful please let me know.
Thanks in advance
BTW: I have read already a couple of threads covering troubleshooting, but they refer to simpler layouts.
I’m also very curious as to why there are no wiring diagram in the manufacturer’s site that matches the model that I have…
