You want the gray needles as they are the diamond ones. The blue
don't last as long or have the same sound quality.

Being a new Seeburg owner, what's the difference between the Seeburg
SAPPHIRE (blue) T-needles, and the GRAY T-needles ? I haven't been able to
find any reference in my manuals for my 220 on which pair I should use?
Thanks - Ace
