Why yes I have, my new Zon Sonus custom five. This bass is the ultimate in playability, comfort, clarity, sound fit and finish.
First I'll start with comfort. This bass fits me just right, it is lightweight and balances nicely. I don't have to fight it or squirm when I'm playing. After a full set of playing my back no longer aches.
The playability of this bass is superb. It has a 34" scale which makes it very easy on my skinny fingers. I have no forearm pain whatsoever, even after several hours of playing.
The sound the sound the sound, I can't say enough about it. I used to play a Modulus Q5. I loved the note accuracy and clarity of these basses. The one thing I was always missing was the warmth. Well, the Zon has plenty of warmth. Now I get a wood tone from a graphite neck. I can get every kind of sound from this bass. Deep deep blues, nasely Jaco-esque burpy-ness, reggae, rock, funk, you name it. This bass can truly do it all.
The fit and finish is about what one can expect from an instrument of this price range. Tight routing, tight neck pocket nice finish.
This is by far the best bass I have ever owned. It is the only bass I have and I have no want for any other. Does this mean I will play this bass for the rest of my days?...no way, it's just what feels really good at the moment. I love my Zon.
