I just picked up one of these, bought used for $650.00 (in excellent condition). It's a lovely bass: I like the look, feel, weight and balance. My very first impression is that I think it will do exactly what I was hoping. My primary basses are an NS Design upright and a Rob Allen fretless. I also have a fretted Ibanez SRH500 (my "poor man's Rob Allen"), which has only a piezo, and an NS Design Radius CR. So I like piezo pickups, especially with tapewounds. My goal with the Portamento was to expand my palette by being able to blend magnetic pickups with the piezo. So far, on the Portamento, I really like the blend of the nasal sound from the bridge pickup, with some thickness from the neck pickup, and depth from the piezo. I have a set of La Bella 750N tapewounds (which is what I use on the Rob and the SRH) on the way and will swap out the flatwounds the Portomento came with. If that ends up sounding too similar to the Rob, then I might go the other direction and slap on a set of GHS Pressurewounds. Electronics work fine and are dead silent. I may eventually replace the pots with better linear taper ones. The E and G strings are a little hotter than the A and D, so I'll monkey around a bit with pickup height and piezo saddle adjustments. The fretboard is interesting... It appears to have some type of coating, but I don't know to what degree it is protective. Does anyone know?
