For me, there is not one perfect set of strings. Just as I like different basses because they have different sounds, I like specific sets of strings on those basses to match their character. These strings were part of my quest to find THE EXACT set of strings that I wanted on each of my basses.
At one time, I had eight different basses and I had different sets of strings on each of them. Some of these strings were extra sets of the ones that I selected for those basses.
Sometimes the differences were subtle and other times quite dramatic. Some strings would sound great on one bass and terrible on another. Other sets would sound just fine on a bass, but it just wasn't the sound that I wanted from that particular bass.
As I am moving overseas, I have had to reduce my bass collection to just two - my Series II and my '59 Pbass. I am keeping the Fodera Diamond XLs for the Alembic, and the Thomastik-Infeld Jazz Flats and Fender Flatwounds for the Pbass.
A few sets of RotoSound Contact Core RS99 went with a John Gray custom 4-string that I gave to my son.
The Alembics were for a 6-string Alembic Rogue.
The DR Hi Beams were for a Modulus 6-string.
The LaBella Supersteps were for a John Gray custom 5-string.
The Trace Elliots were for a 5-string Alembic Rogue.
I hope everyone else has as much fun as I did trying out all these strings!
