The SolidGoldFX Beta, essentially mirroring the Zeta but re-calibrated for the bass, uses a JFET preamp and germanium clipping to build dynamic and musical, tube-like drive tones from mild Motown to full, roaring overdrive. Designed to give you warmth and just enough punch to take your rig above and beyond without being overly aggressive, the Beta gives you tailor-made EQ and tone that will spice up your bass' sound with a sumptuous overdrive.
