Spector EURO4RSTSIENNA Euro 4 RST Electric Bass - Sienna Stain MatteThe Euro RST series brings Spectors classic design into the modern era with updated tonewoods, enhanced electronics and a fresh palette of exclusive stain options. Neck through construction has long been central to the Spector design and the Euro RST takes this concept to the next level with a three piece roasted maple neck and fingerboard. The roasting process not only gives this design a distinct look, but offers enhanced stability and rigidity.
