I got a set of Thalia Teflon pads. They sound very lively... and my capo always matches my fretboard radius! These do wonders for acoustic or electric guitars!

If you want to experiment on different tones create by different materials of the fret pads, the Teflon option is good for you. It creates a brighter, more transparent, crispy tone than the standard rubber. Both materials work very well, it really depends on your taste. Different pieces may work better with a different fret pad! Keep trying!

Just before Xmas, I bought 2 Thalia capos (one was a present) ... both Blue Abalone w the black finish, as well as the Teflon tuning kit upgrade for both. Both capos were so gorgeous I had to spend days agonizing over which one to give away. The Teflon upgrade does improve the sound (at least on my friend's & my guitars): clearer tone, sweeter, slightly more volume. Every guitar is different, tho, so for some the standard rubber might be the ticket.

As always the team at Thalia were absolutely excellent in everyway. Hands down the best quality and beautiful capos. Great customer service and experience all around.

Outstanding quality
& always great service with Thalia
