Hartke TX300 — 300W Class D Bass Amp Head in a 2.3 kg Aluminum Chassis

The Hartke TX300 is a 300-watt Class D bass amplifier head built for bassists who need serious output without the weight of a traditional amp. Delivering 300 watts at 4 ohms from a 2.3 kg anodized aluminum chassis, this head answers the call for players on the move. For working bassists who want gig-ready volume in a portable package, this model is an excellent choice.

Shape Circuit and Onboard Compressor — Tone Tools That Punch Above Their Weight

Two design choices set this head apart. A continuously variable contour filter, the Shape control, sweeps between 185 Hz and 860 Hz with a -20 dB notch for tailored midrange sculpting. The fixed-ratio 1.6:1 onboard compressor evens out slap-pop dynamics — no outboard pedal needed.

Power Section and I/O — Stage-Ready Connections in a Compact Frame

Connectivity matters as much as wattage on a gigging amp.

• Rated Output Power: 300 W @ 4 Ω / 200 W @ 8 Ω — headroom for a 4-ohm cab or an 8-ohm pairing
• Balanced XLR Direct Output: 125 Ω — runs to a mixer or audio interface without a separate DI box
• The effects loop provides 1/4" jacks for preamp out and power amp in, allowing you to patch in time-based effects easily.

Preamp and Tone Shaping — From Clean Fingerstyle to Thick Fuzz

The front-panel preamp is where this amp earns its reputation.

• Drive Circuit: variable from clean warmth to full fuzz — covers clean, mild breakup, and aggressive overdrive without a pedal
• Compressor: 1.6:1 fixed ratio, threshold off to -30 dBu — evens out slap-pop dynamics and protects the cab
• The 3-band EQ offers active control with Bass ±16 dB @ 30 Hz, Mid ±16 dB @ 700 Hz, and Treble ±16 dB @ 6.5 kHz, complemented by the Shape contour.

Chassis and Footprint — Aluminum Build, Gig-Bag Friendly

At 2.3 kg and 365 mm wide, this head suits bassists who would rather not lug a heavier amp to a one-set gig.

• Chassis: anodized aluminum — keeps weight down and resists stage wear
• Weight: 2.3 kg — light enough to carry in a gig bag alongside a compact cab
• With dimensions of 161 mm × 365 mm × 273 mm, it sits securely on top of a 1×12 or 2×10 cab without any overhang.

Who the TX300 Suits — Gigging Bassists, Recording Players, and Practice-Room Users

Working bassists who play a mix of club dates, rehearsal rooms, and recording sessions rely on this versatility. Players who already own a compact cabinet — a 1×12 or 2×10 — gain a 300-watt head that pairs with it cleanly. Practice-room users benefit from the headphone output and aux input, while the balanced XLR direct out fits those splitting signal between a stage cab and the front-of-house mix.

Hartke and the TX Series — Aluminum-Chassis Bass Heads for the Working Player

Hartke built its reputation on aluminum-cone bass speakers. This model sits between the smaller TX112 combo and the larger LX-series tube-preamp heads, offering a portable 300-watt option. It is best paired with the HL112 HyDrive cabinet for a ready-to-gig mini-stack.
