Modifications and Upgrades


There are many modifications and upgrades to improve the performance, playability and tone of your guitar.

From simple jobs that make a big difference right up to complete overhauls including finish, Fretco have the parts, tools and advice to help you enhance and add value to your instrument.

You may be surprised that with only a little time and effort, your favourite guitar may not need replacing with a better one after all!

Many well known (and well made) brands of guitar straight off the shop floor can still be significantly improved with just a few small parts and the right set of pickups.

We have some suggestions for you on this page, however the range of options is so large we couldn’t possibly list them all.
