Congrats, once again! That's been my experience with a Starfire with this kind of modification. I think the bridge alone adds a huge amount to the basic tonal improvements. The original Starfire bridges are a huge source of loss of energy. With the sustain block and brass bridge, the whole bass resonates. I can only imagine that the ebony fretboard increases the crispness and definition and I'm sure the electronics are just superb. With so much going on with the harmonic structure of the tone, the filters have a lot of material with which to work. I love being able to focus in on different parts of the attack of each pickup with the filters. This is one bass I really want to experience in person! Thanks for doing this.
Oh yeah, it looks really cool, too!
