Thanks for the info. I looked into the Dark Star pickups and it appears the DS-1 model is compatible with the Vox violin body that I am re-building;
Dark Stars come in 4 different pole spacings:
1. The DS-1 model has a pole to pole spacing of .640 (16.25mm).
This model is what Guild used on the '60s Starfires.
2. DS-2 has a wider pole spacing of .680 (17.25mm) for Guild and DeArmond reissue bridge position pickups. This model will fit most other short scale four string basses as well.
*The Hagsrom Coronado IV bass came with both pole spacings. (DS-1 & DS-2)
3. The DS-3N (neck) is popular with Fender P type basses or long scale basses with similar string spacing in the mid body position with a pole spacing of .710 (18mm)
4. The DS-3B (bridge) has the widest pole spacing at .750 (19mm) pole to pole which fits the bridge position of most long scale basses.
5. The 5th choice is the DS-3ND which was developed for the Lakland Decade bass to be used in the extreme neck position of long scale basses. It has a pole to pole spacing of .680 (16.25mm - same as the DS-2) but is matched in DC resistance to the other DS-3 models. Matched DC resistance is best for hum-canceling.
Any combination of the DS-3 models can be made into an RWRP set.
The DS-5B (18mm) and DS-5N (17mm) 5-string models will be available soon.
I sent Fred Hammon an email to confirm the DS-1 and get his advice on the rebuild.
I think the below link will show a photo took last week.
