A better bass is the best teacher you're ever gonna get.

 The J4 Numero Uno and J4 Eldorado are my own two MüB, custom-fit to my playing style which spans from finger style to classical guitar arpeggios plus some slap tweaks of my own. Tone-wise, I like a lot of snap and growl with a P-bass kind of bottom thrown into the mix. Action is very low cuz I like to get carried away.

It's In The Neck.

At MüB we are convinced that a lot of our basses tone comes from the neck. All that snap, articulation, attack and nearly infinite sustain? All in the neck. So we put a lot of thoughts and money inside each and every one of those little buggers. And to make sure they fully deliver we extend the neck pocket all the way to the first p-up, however deep into the body that might be.
