This is one of 3 unique basses. It is a replica of Sander’s personal bass. Outer appearance, that is, because Sander has a Bebop. We have made 3 replica’s, a Bebop 4, Bebop 5 and a Soulmate 4. This is Sander’s signature. Apart from killer looks, there’s killer sounds as well. There’s a NP4 and a NJ4SV by Nordstrand, for hum free, bold classic sounds. This bass is a stunner in every way imo.
