Key Features Of The Ampeg Rocket Bass RB108 Explained
Signature Ampeg Tone
Ampeg is known for its thick, supportive low end and slightly rounded highs. The RB108 captures that character surprisingly well for a compact practice amp. It doesn’t sound sterile or thin — it retains warmth even at lower volumes.
Ultra Hi / Ultra Lo Switches
These preset tone-shaping switches make quick adjustments easy:
- Ultra Lo boosts low frequencies while reducing mids for deeper thump
- Ultra Hi enhances clarity and presence
This makes it beginner-friendly while still offering tonal flexibility.
30 Watts with 8” Speaker
The 30W output paired with an 8-inch speaker provides noticeably fuller low-end response than smaller 10–15W amps. It’s suitable for bedroom practice and small, controlled rehearsals, though not for loud gig environments.
Practice Features
The headphone output supports silent practice, and the AUX input allows players to jam along with music or backing tracks.
Build Quality
The RB108 feels solid and durable. The cabinet design reflects Ampeg’s classic styling, and the amp has a more “serious” feel compared to ultra-budget practice amps. Knobs and switches feel sturdy, and the enclosure is robust enough for regular transport to lessons or rehearsals.
