Whilst choosing your frets, there are two key things to consider; fret size and material.
The size of the frets has a large influence over how the guitar plays. Smaller frets tend to be found on vintage and traditional style guitars and larger (jumbo) frets on more modern instruments. This is because they make it much easier to bend the strings as the string is no longer in contact with the fretboard, and consequently, the friction is reduced. It's not all good news though. String bends can be harder to control, so over shooting that perfect pitch can be an issue. Another issue is that if you push too hard, the note can sound slightly sharp as you are essentially bending the string over the fret. If you push hard, Jumbo frets probably aren't for you, or will take some getting used to. The opposite is true with small frets. Tuning tends to be good, but bending is harder.
Medium Jumbo frets are a great middle ground, which is why they come as standard on our Semi-Custom guitars.
We currently offer two fret materials Nickel Silver and Stainless Steel.
Stainless Steel has several advantages over Nickel Silver. Firstly, longevity. With Stainless frets you can expect your fret job to last for decades. This is because it is much harder than the Nickel Silver. Consequently, wear is reduced. This keeps your fret crown in better condition over the years, resulting in better intonation and easy bends for the life of the guitar. Secondly, they tend to stay more polished, resulting in a smoother feel whilst bending. Finally, the tone is said to be slightly brighter. There is a couple of downsides too. As they are much harder, the take longer to work and get through more tools resulting in a higher price. This price increase can be offset against a future fret job which can set you back around £300. The final downside is that due to its hardness, you may break strings a bit more regularly. To be honest you probably won't notice a significant difference.
This is the traditional fret material which, up until very recently, was used in most production instruments. It is easy to work and therefore cheaper than Stainless Steel. Its tone is said to be slightly less bright that Stainless frets, but you'd be hard pushed to tell the difference.
