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 is a bass combo amplifier series offering models from 30 to 500 watts, designed for gigging bass players who need straightforward, powerful tone at a competitive price. Three preamp voicings — flat, modern, and classic — cover clean through Bassman and SVT-adjacent sounds. A semi-parametric sweepable mid control alongside three-band EQ enables precise frequency management for different rooms and instruments. A drive control mixes overdrive, distortion, or fuzz into the clean signal. A response control simulates different valve stages, adding tube-like character to the solid-state design. Onboard compressor, chorus, and octave effects complete the feature set for a self-contained practice and gigging bass tool.
