Wiring up GFS MMB pickup to Belcat Pre Amp
Having lots of fun trying to work out best way to wire up on blend pot that comes with the eBay 'Belcat' pre amp.
Kit supplied PUP had 5 wires where one was outer shield and theoretically should have allowed for front coil, rear coil isolation via the blend pot, and when centered it was in series as a humbucker. Played around with that PUP over a few days and could never get that to happen plus the wires were so thin they broke off at solder joints way to easy.
GFS replacement arrived a couple of days ago and this one is 4 wire but technically 3 as the outer shield does not share a signal with the 3 inner Red, Black or White wires. This probably means I can only coil split in one direction. When measuring things the rear coil lines up pretty close to same position as bridge J Bass PUP (10 mm further forward) whilst front coil is about 34 mm further towards neck. At the moment it seems I have wired in series as nothing is happening on either left or right side of center detent. Still sounds quite meaty and happy with that sound but seeking some guidance on which wires to swap around as my patience is almost at an end. At this stage I am leaning towards splitting to front coil as hopefully that should still retain more lower mids and maybe sound a bit like P Bass, and if I want J Bass sound I already have one of those.
Here are a couple of photos and diagrams and happy to wait for some feedback and guidance before heating up the soldering iron again. Last handwritten diagram is where things are at...
Thanking you in advance.
Cheers, Waz
