Dunlop 227

I'm a dedicated slide player and I have a bag of various slides and things I use for slide. This one is great for certain things - it grips the entire neck, I like the tone. The curved shape definitely makes a difference on necks with a smaller radius (old fenders) and is great for when you need to cover all the strings all the time. It serves a purpose. If you are serious about slide playing I'd recommend.

This slide is great!
Well built.
A quality slide for guitar necks that have some rounded radius.
The concave slide makes it easier to play slide on standard guitar setups where the strings are not flat.

I also use the "Rock Slide TRS-SB Small Brass Slide" (from Thomann) and put it inside the larger concave slide, to make the concave slide to fit the pinky finger perfectly.

I'd recommend buying both together.

This slide made it a lot easier for me to play slide guitar.
The construction with the concave outer shape has been absolutely amazing for my playing.
I have played it a lot over the last couple of years and it's starting to look a little worn, but works like a charm still.

There are better slides out there ... I ordered this twice due to the chaotic delivery methods of Thomann. Unfortunate.
