TC Electronic Thrust BQ500 — 500-Watt Portable Bass Amplifier Head

The TC Electronic Thrust BQ500 is a 500-watt Class D micro bass head built for bassists who refuse to choose between power and portability. Housed in a rugged steel chassis weighing just 2.3 kg, this compact amp head slips into a gig bag or backpack yet still delivers enough headroom to fill small and medium-sized venues. The Thrust BQ500 pairs a high-voltage MOSFET preamp with a cutting-edge Class D power section, giving players the warm, touch-sensitive response of a tube amp without the back-breaking weight.

Standout Features: MOSFET Preamp and Thrust Compressor

What separates the Thrust BQ500 from other micro bass heads is its high-voltage MOSFET preamp, which reproduces the dynamic feel and harmonic richness of classic tube designs in a solid-state package. The single-knob Thrust compressor circuit sets the dynamic range of the playing with one twist, delivering maximum punch that cuts through any mix. A passive/active switch on the front panel optimizes the preamp input for both vintage passive pickups and modern active electronics, so the amp responds correctly regardless of the instrument.

Power and Portability — Class D Efficiency

The Class D amplifier topology is the reason this head weighs so little yet still pushes 500 watts into a speaker cabinet. Players hauling gear to small club gigs, rehearsal rooms, or hotel sessions benefit from a chassis that measures roughly 255 × 69 × 233 mm and tips the scales at only 2.3 kg. The auto-ranging universal switch-mode power supply accepts mains voltage worldwide, so the same head travels from a European rehearsal space to a North American tour stop without missing a beat.

• Power Output: 500 W Class D — fills small to medium venues when paired with a 4 ohm cab
• Chassis Weight: 2.3 kg — light enough for one-handed carry to the stage
• Dimensions: 255 × 69 × 233 mm — fits in a backpack or amp gig bag
• Power Supply: Auto-ranging universal switch-mode — worldwide operation without voltage switches

Tone Shaping — 4-Band EQ and Thrust Compressor

The 4-band EQ section is the player's main sculpting tool, with parametric mids sitting alongside the bass, low-mid, high-mid, and treble controls for surgical or broad tonal moves. The single-knob Thrust compressor sits next to the EQ, letting bassists dial in tighter, more even dynamics for slap, fingerstyle, or pick playing. A gain knob drives the MOSFET preamp into mild saturation when pushed, while the master volume sets the overall stage level.

• Preamp: High-voltage MOSFET — tube-like touch dynamics and harmonic warmth
• EQ: 4-band with parametric mids — broad or focused tonal shaping across the spectrum
• Compressor: Single-knob Thrust circuit — instant dynamic control for punchy, even bass lines
• Pickup Switch: Passive/active — optimizes input impedance for any bass

Connectivity — DI, Headphone, and Speaker Outputs

On the rear panel, the balanced XLR DI output with pre/post EQ routing feeds a FoH console or audio interface with the player's full tone, EQ, and compression already dialed in. The locking speakON speaker output accepts a 4 ohm minimum load for secure connection to cabinets on stage. A 1/8-inch headphone jack with built-in speaker emulation lets players practice silently with the sound of a real cabinet, while the 1/8-inch aux input accepts backing tracks from a phone or media player.

• DI Output: Balanced XLR with pre/post EQ switch — direct-to-console or interface recording
• Headphone Output: 1/8-inch with speaker emulation — silent practice with cab-style response
• Speaker Output: Locking speakON (4 ohm minimum) — secure stage connection to bass cabinets
• Aux Input: 1/8-inch — jam along with backing tracks through the amp

Who Is It For — Touring Bassists, Gigging Players, and Home Practice

The TC Electronic Thrust BQ500 is the right choice for gigging bassists who need genuine 500-watt power in a head that disappears into a gig bag. Touring players benefit from the universal power supply, rugged steel chassis, and protection against short circuits, thermal overload, and low speaker impedance. Home players gain a full-featured practice tool thanks to the headphone output with speaker emulation and aux input, while studio bassists route the balanced DI straight into an interface for tracked sessions. Backed by TC Electronic's 3-year warranty and engineered in Denmark, the Thrust BQ500 covers club dates, rehearsal rooms, and late-night hotel practice in one compact package.

TC Electronic — Danish Engineering for Bass Players

TC Electronic has long been associated with professional studio and stage signal processing, and the Thrust series extends that engineering pedigree into the bass amplification category. Designed and engineered in Denmark, the BQ500 carries a 3-year warranty program and reflects the brand's focus on portable, road-ready bass tools. The Thrust line pairs the company's well-known compression and tone-shaping expertise with a Class D power platform, giving bassists a modern, lightweight alternative to heavier traditional bass heads.
