Hartke TX7500 800W Bass Amplifier
The Hartke TX7500 is an 800-watt bass amplifier head built to handle everything from local gigs to full studio sessions. Weighing in at just 8.5 pounds, this lightweight, all-metal amp gives bass players serious headroom without the back strain of a traditional head. Sam Ash Gear Experts know bass amps live a hard life — thrown in vans, stacked on cabinets, run for hours on end — and the TX7500 is built with that reality in mind, pairing genuinely useful tone-shaping controls with road-ready construction. Whether you're running a wall of cabinets at a club show or tracking direct in the studio, the TX7500 gives you the power and flexibility to get the job done.

Serious Power, Studio-Ready Connections
At the core of the TX7500 is an 800-watt Class D power section rated at 4 ohms, more than enough to drive a full stack or a single heavy cabinet with authority. Both 1/4" and SpeakOn outputs mean it connects to virtually any bass cabinet on the market, and built-in fan cooling lets it run at full output for as long as the set demands without overheating concerns. For studio work, the TX7500 includes a balanced XLR direct output with a ground lift toggle for a clean, hum-free signal straight to the board, plus a 1/4" effects loop with send and return jacks for wiring in external processors. It's a rare amp head that's genuinely built for both the stage and the control room
Dial In Your Tone
Tone-shaping on the TX7500 starts with dedicated Drive, Compressor, and Gain controls, giving players everything from a clean, punchy low end to a driven, aggressive growl. A graphic EQ combined with Brite and Shape toggles lets you sculpt the midrange and add sparkle or scoop without hunting through menus, while a 1/4" tuner output keeps you in tune between songs without breaking your signal chain. Output and Direct Out mute switches make silent instrument swaps and line checks simple, a small but appreciated detail for anyone who's had to scramble mid-soundcheck.
Built to Travel
Samson's Hartke team built the TX7500 around a rugged, all-metal chassis that can take the abuse of van loads and stage moves without complaint, while still keeping the whole unit under 9 pounds. A built-in carry handle makes it easy to move between the van and the stage, and large rubberized feet keep the amp firmly planted on top of a cabinet even during the loudest shows. For bass players who need pro-level power without adding another heavy case to the load-in, the TX7500 is a lightweight amp head that doesn't cut corners on tone or durability.
Why We Love This
Bass players appreciate the TX7500 because it doesn't force a tradeoff between power and portability. Eight hundred watts is plenty for most stages, but the amp still weighs under nine pounds and fits easily into a gig bag. The Drive and Compressor controls make it simple to shape tone on the fly, while the XLR direct output means it goes from a loud club gig straight into a studio session without extra gear.
