What Vinni has just posted is entirely true. These picks are very fast. The material seems to just slide over the strings and is very very smooth. The grip is very nice. My fingers seem to just stick to the pick and don’t slide at all. Overall the pick is very comfortable to use. Sound wise single notes remind me more of finger-plucking tone (but still retaining the volume of using a ‘normal’ pick) than using a conventional pick. Very full and more bass than treble attack. Very nice sounding.
