Compact in size but commanding in output, the Phil Jones Bass Suitcase Compact BG-400 bass combo amp delivers studio-grade clarity and gig-ready power in one transportable design. Housing four custom-designed 5" Piranha speakers driven by a 300-watt class-D amplifier, the BG-400 achieves remarkable efficiency and punch for its footprint—rising to 500 watts when paired with a Compact 4 extension cab. Its dual-channel preamp and responsive three-band EQ give you precision control over tone, allowing seamless adaptation between active and passive basses or fingerstyle and slap techniques. Designed with working musicians in mind, the Suitcase Compact mirrors the dimensions of the Compact 4 enclosure for modular expansion while maintaining a solid, low-end presence that fills small venues with ease. With rugged construction, detailed controls, and unmistakable clarity, this combo stands as a professional-grade solution for bassists who demand portable power without compromise.

Class-D Power Amp Drives Four Piranha Speakers for Punchy Output

The class-D power amp inside the Suitcase Compact uses an ultra high-energy power supply, directing nearly 95% efficiency to the speakers. Each of the four Piranha drivers moves air with surprising punch and clarity, resulting in a tight low end and crisp mids. Adding a Compact 4 external cabinet boosts output to 500 watts, giving bassists extra headroom for louder stages or outdoor shows. The amp’s high-efficiency design ensures consistent performance, so your sound stays powerful throughout long sets.

2-Channel Preamp With 3-Band EQ Shapes Signature Tone

The dual-channel preamp offers separate input levels and a clear three-band EQ for each channel. Bass, mid, and treble controls respond quickly, making it easy to fine-tune your tone for different instruments or playing styles. A limiter switch keeps peaks under control, while the EQ’s transparency means you hear the true sound of your bass. This layout gives precise control over your signal, helping players stand out in a mix or adapt to changing stage setups.

Comprehensive Controls and I/O Support Flexible Setups

This combo amp includes practical features for flexible setups: two inputs, D.I. output with ground lift, effects loop, tuner out, and preamp out. The front panel offers straightforward control over master volume, auxiliary input, and headphones for quiet practice. External speaker connectivity uses a Speakon jack for secure connections. Simple switches let users mute the amp or select passive/active input levels, so quick adjustments don’t interrupt rehearsal or performance.

Solid Construction and Compact Size Support Heavy Use

The unit measures 14.2 x 12.4 x 13.4" and weighs 40 lb., making it easy to carry without sacrificing durability. Sturdy materials and reinforced corners protect the amp from impacts during transport. The housing resists scuffs and scratches, while the speakers and electronics withstand frequent use in practice rooms or on stage. This build quality means players can rely on the amp for consistent sound, gig after gig.

Bassists looking for focused punch, detailed EQ, and road-ready build will find the Suitcase Compact BG-400 supports confident playing in practice or live settings.
