“Phen” J series 4-string

Developing a new 4 string bass model on the basis of an existing model is a delicate matter. But this is exactly what I wanted to do in creating the J series. I wanted something a bit more mainstream, more acceptable and simplified, while at the same time keeping the specific feel, contour and look of the original Phen.

“Thumb nest” is a very special feature, which I invented in 2011. To indicate KD’s trademark, I usually make a small wood carving in a certain place on the back side of the headstock, somewhere between the tuners. This time I decided to do something completely different. I turned the decorative element into a very useful and helpful feature, which I called a Thumb nest.
I meet musicians every day and all of them have their own biological individualities. Like the length of the fingers or the way they hold the neck while playing. Due to these specifics, for some musicians playing can be met with serious difficulty. So I decided to do something in order to find a solution to the problem. That’s when I came up with the Thumb nest idea.
It took me some time experimenting with it, but the outcome was more than successful! It provides incredibly easy access to the first frets, making the hand flow on the neck and unleashes a great freedom while playing. And the most important thing – it makes the musicians Happy!

NOTE! Depending on the source of light and the type of monitor, the color might look slightly different!
