i bought a spector 5 used from GC and i LOVED the strings on them.
problem is i dont know what they were so heres some identifiers:
-Black thread
- very smooth feeling on the fingers, not rough like my DR hi beams. theyre not flatwound bt almost like a nice compromise between flat and round
-mellow deep tone . not super bright
regular metal ball ends
hope this helps and SOMEONE knows what they are..i want them on my new jazz
