Features and functionality
-
The Fender Rumble 40 is praised for its midrange contour switch and overdrive, offering more tonal options compared to the Ampeg RB-108's simpler 3-band EQ.
Source
User experience
-
The Ampeg RB-108 is appreciated as a portable practice amp with a tone likened to the classic 70s Ampeg sound, especially loved by those with multiple amps.
Source -
Owners suggest that an amp with at least a 10" speaker and 40 watts, such as the Rumble 40, is necessary for effective bass reproduction and versatility in small band settings.
Source
Use cases and applications
-
It's highlighted that an 8" speaker, like in the RB-108, is ideal for home practice but insufficient for playing with others or in a band setting.
Source -
The RB-108 can be effectively used for recording by combining a DI box and miking the amp with an SM57 to capture both clean lows and distorted highs.
Source -
Miking the RB-108's 8" speaker is viable; if unsatisfactory, the DI track can serve as a reliable fallback.

Superior Bass Practice Amplifier
Ampeg has always been my favorite brand for bass amplification. This little 8" 30-watt guy is no exception. The SGT circuit is usable but not outstanding.
It's well-made and loud enough for practice without disturbing your entire household. The headphone jack is a definite plus.
It's not fancy but it's solid.

Excellent sound quality for the price
I've always been a fan of Ampeg's amps, and this one doesn't disappoint. It's a practice amp so the features are bare-bones, but it sounds incredible for such a cheap amp. It's not short on headroom, either. I keep the volume between 3 and 4, which is comfortable for a bedroom practice space, and it stays nice and clean if that's what you're looking for. The Super Grit Technology overdrive is nice enough, but I wasn't super impressed with it on this amp (I've tried the other amps in this series and the louder the amp, the better it sounds). I find it overdrives better by boosting the midrange and cranking the volume, but your tastes may vary.
For under $200, you can't beat this for a practice amp. Great headroom, good overdrive, and a 3 band EQ that will conjure up nearly any tone you want. I also like hitting it with a fuzz pedal for maximum doom.
