I have them on a MIA Telecaster and they stay in tune and have good sustain

All of the different types of strings that Fender has bullet ends on, offer great sustain and tuning stability

The bullet ends achieve better sustains and enhance sound noticeably.

The sound is rich and the sustain is pure beauty

The bullet ends are perfect for a stat, and designed for it, and sustain is excellent.

Their not necessarily brighter, just more defined with better sustain

They seat snug and enhances sustain

The brass bullet end will not break or unravell and transfers a more solid tone and sustain
