Which TSBS - old ones have Seymour Duncan’s, new ones have Sandberg black label pick ups?
In feel they will be similar to a TT4 variations of different pieces of timber aside which you get per bass, hence the neck has a ‘slightly’ larger profile in that the nut width on a DK is 37mm and a TSBS/TT4 is 38-39mm.
All sig models have a slightly different pick up placement compared to say a standard TT even if it’s a few millimetres , for example the DK bridge pick up is closer to the bridge similar to the 70s position so a little more ‘bark’
TSBS is a great bass
Probably the new ones. I love that relic’d yellow finish and maple neck with perl inlays. I had a Fender Marcus Miller with a similar neck which was great. Unfortunately it weighed over 10lbs so had to go!
