I’ve just given it a try with a P bass too, i like the amount that it dampens, it’s not too much, seems quite even across the strings aswell, quite pleased with it
I’ve never really liked that earlier style P bass , i much prefer the last year 57- 58 onwards, but I’ve never played one, maybe if I did It might change my mind
Ive been looking at a few 66 Precisions so Ive been using my AVRI 62 more lately to see if I can get comfortable with the wider nut , it’s going alright really, can I ask what it is that your not liking about the sound or playing of yours
