Revoltage RV-40B Bass Combo Amp — 40W of Tonal Control for Practice and Stage

The Revoltage RV-40B is a 40W solid-state bass combo amplifier built for bassists who want a single rig covering bedroom practice, rehearsals, and small-stage performances. A 10-inch speaker sits inside a compact 42.5 cm × 44.5 cm × 30 cm cabinet, keeping the footprint manageable without sacrificing low-end weight. This model is the right choice for bassists who need an affordable, feature-loaded combo that grows with their playing.

What Sets the RV-40B Apart in the Budget Bass Combo Category

Two features separate this combo from typical entry-level bass amps. With its 4-band EQ and split mid frequencies, you get independent control over Mid Frequency and Mid Level, a level of tonal shaping usually reserved for higher-tier combos. The built-in compressor provides on-demand dynamic smoothing for slap and pop techniques, no external pedal required.

Power and Speaker Configuration — Headroom for Practice and Small Gigs

Combining a 40W solid-state power stage and a 10-inch speaker, this combo produces enough volume and low-end response for home practice, band rehearsals, and intimate club performances. Solid-state circuitry helps keep weight at 12 kg, making transport between home and rehearsal simple and reliable.

• Power Output: 40 W — solid-state headroom for rehearsals and small gigs
• Single 10" speaker tuned for full-range bass response with enough air movement for slap and pick playing
• Power Amp Electronics: Solid State — consistent tone and lower weight than tube designs

Tone Shaping — 4-Band EQ with Split Mids and Onboard Compressor

Six front-panel controls give direct access to the most-used tone parameters. The 4-band EQ includes Bass, Treble, and split Mid controls for surgical midrange shaping. With a dedicated Gain knob for input level and grit, and a separate Volume control, it's easy to dial in your sound. The onboard compressor keeps dynamics even for slap and pop playing.

• Controls: Gain, Bass, Treble, Mid Frequency, Mid Level, Volume — full 4-band EQ plus input gain
• With the built-in compressor, players can smooth out dynamics for slap, pop, and lead playing without needing an external pedal.
• Number of Channels: 2 — switch between clean and overdriven voices

Connectivity and Practical Features — Silent Practice, Play-Along, and Direct Output

Modern bass workflows are supported with headphone and AUX inputs. Plugging in headphones enables silent practice at any hour, and the AUX input allows for jamming along with backing tracks from your phone or MP3 player. The balanced DI output sends a clean, low-impedance signal directly to a mixer or recording interface, ready for stage or studio.

• DI Output: Yes (balanced) — direct feed to mixer or audio interface
• Headphone Output: Yes — silent practice without disturbing others
• AUX / MP3 Line In for play-along with backing tracks from a phone or MP3 player
• Effects Loop: No — onboard compressor covers basic dynamics
• Footswitch Input: No — channel and EQ set manually on the top panel
• Weight: 12 kg — manageable for transport to rehearsals

Who the RV-40B Is Built For

This combo is a practical solution for beginner and intermediate bassists looking for one amp to cover practice, rehearsal, and small gigs, without the need for extra pedals. Its onboard compressor and split-mids EQ provide space for tone development, and the DI output makes it fit for direct recording or live sound. Bassists seeking a compact, lightweight rig with robust connectivity will find it adapts well from bedroom to stage use.
