500W Ultra-Compact Class-D Bass Amplifier Head

Pure Power, Cutting Clarity & Illuminated Style

Lightweight, powerful, and engineered to cut through any mix.

Designed for the modern bassist, this ultra-compact amp head packs 500 Watts of raw, dynamic Class-D power into 4 Ohms while weighing a mere 2.2 kg. Built around pristine, high-grade operational amplifiers (Op-Amps)—and completely tube-free—it delivers maximum transparency, lightning-fast transient response, and an uncolored, punchy tone.

Housed in a compact enclosure (60 x 250 x 190 mm) topped with a transparent top cover and a backlit illuminated logo, this amplifier looks as striking on stage as it sounds.

Total Tone Mastery: 3-Band EQ & Variable HPF

• Bypassable 3-Band EQ: Sculpt your sound with a musical 3-Band EQ, or hit the EQ Bypass switch to route your pure instrument signal straight to the power section—perfect for tone purists and pedalboard users.

• Variable High-Pass Filter (HPF): Bad stage acoustics can turn your low end into mud. The integrated adjustable HPF lets you strip away unwanted sub-bass frequencies, giving you:

  • Maximum Low-End Punch: Tighter, articulated bass that cuts through full band mixes with ease.

  • Room Correction: Eliminates stage boominess in acoustically challenging venues.

  • Speaker Protection & Efficiency: Saves amplifier headroom and prevents speaker drivers from harmful over-excursion.

Stage, Studio & Practice Ready

Whether you are performing on main stages, tracking in the studio, or practicing at home, this head provides ultimate versatility:

• Studio-Grade DI Output: Features dedicated volume control and a Ground Lift (GND) switch to instantly eliminate ground-loop hum when connected to FOH or recording interfaces.

• Professional SpeakON Output: High-current twist-lock speaker connection for maximum power transfer and stage reliability.

• Bluetooth Connectivity: Wirelessly stream backing tracks or practice songs directly through the amplifier.

• Audiophile Headphone Output: Delivers high-fidelity, full-range tone for quiet late-night practice sessions.
