Drat !
I had to Google to understand this word!! 😄
I had stringed with flats and used yesterday at rehearsals with my band. The bass is very well balanced, no neck diving, but I was not fully satisfied with the sultain. I like to play few long lasting notes and I guess that roundwound will be better. I just ordered Thomastick and Rotosound strings. I also suspect that the distance from poles is a key. Apparently the magnetic field is strong enough to kill sustain. I am Going to lower a little bit the poles to see if sustain improves.
The sound depends a lot on wbere you pluck the string. If you play on the pickup you have a lot more low frequencies than if you play a little closer to bridge. Even a little makes a lot of difference in sound.
As some of you in the past I tried to reproduce some bisonics, the badsonics mentioned in my signature that use ferrite beads instead of laminations. My peavey T-40 wnere I installed has a similar sound compared to the Starfire. By sure it had more highs due to the different location of the pickups but in my opinion the idea behind the construction of the pickup was correct.
And finally, no I will not give to anyone or share my new 1967 lover! Sorry guys
