The Ampeg Rocket Bass RB-115 is a 200-watt, 1x15-inch bass combo amplifier with an SVT-inspired preamp and Ampeg's Super Grit Technology (SGT) overdrive circuit. The 15-inch Eminence speaker delivers warm, massive low-end with a slightly scooped midrange and SVT-like warmth in the high end. At 34 pounds and priced around $549, it is the most stage-capable single-driver model in the Rocket Bass series, suited to players seeking their first professional-quality Ampeg combo for small to medium venues, rehearsals, and recording.
The Blackstar Unity Bass U120 is a 120-watt 1x12 solid-state bass combo amplifier built for stage-ready performance. A custom-designed Eminence Opus 12-inch speaker in a closed-back cabinet delivers tight, responsive low-end with punchy midrange. Three preamp voices — Classic for vintage warmth, Modern for high-headroom clarity with extended low end, and Overdrive for harmonically rich grind — are complemented by a three-band EQ with semi-parametric mid control and a Response control selecting between Classic, Modern, and Overdrive power amp behavior. Built-in compressor and chorus effects round out a fully self-contained gigging bass amplifier platform.
