The difference between 6105 and 6150 frets is the size and shape of the fret wire.
6105 frets are considered to be a “vintage” style fretwire, and are slightly smaller in size than the 6150 frets. They have a lower profile and a narrower width. This makes them more comfortable playing, particularly for players with smaller hands.
They also provide a more responsive and precise feel when playing, which can be beneficial for certain styles of music such as fingerstyle and jazz.
6150 frets are considered to be a “modern” style fretwire, and are slightly larger in size than the 6105 frets. They have a higher profile and a wider width.
This can make them more durable and long-lasting, but may also make them feel less comfortable for playing, particularly for players with smaller hands.
They also provide a more aggressive and forceful feel when playing, which can be beneficial for certain styles of music such as rock and metal.
Ultimately, the choice between 6105 and 6150 frets will depend on the player’s preference and the type of music they play. Both types of frets have their own set of pros and cons, and it’s a good idea to try out both and see which one feels and sounds better to you.
