Critic Reviews

Ampeg Rocket Bass RB-108 and RB-110 review | MusicRadar

musicradar.com

Ampeg's Rocket Bass RB-108 and RB-110 deliver a compact yet surprisingly powerful sound, blending affordability with classic Ampeg charm. Their portable design and versatile tone options make them great for home practice or small gigs. However, the lack of a footswitchable SGT feature and a slight dip in bass response due to size might deter some. Still, the simplicity of their controls and the warmth of the Super Grit Technology deliver an impressive performance, particularly for rock bassists. For those seeking a reliable, user-friendly amp, these combos are hard to beat.

Ampeg Rocket Bass RB-108 and RB-110 review | Guitar World

guitarworld.com

Ampeg's Rocket Bass RB-108 and RB-110 combo amps deliver portable and user-friendly designs, ideal for home and small gigs. The standout features include the SGT overdrive circuitry, which enhances sound character without the heft of tube amps. However, bass projection is limited due to their smaller speaker sizes, making them less suitable for louder environments. While they excel in usability and portability, expect a mid-bias sound profile that may not satisfy everyone’s low-end cravings. Overall, these amps are solid choices for casual players, but they fall short in power and depth for more demanding settings.
