Description
If you’ve stood behind a GK head at a loud gig, you know the deal: this thing just works. The 1001RB-II runs on an extremely high-current power supply paired with matching power amp circuitry, so there’s no current-limiting circuitry standing between your fingers and full output. That matters more than it sounds — it’s the difference between an amp that compresses and smears under load and one that stays punchy when you dig in.
- 700W to the woofer, 50W to the horn, split by an electronic crossover for clean, seamless 2-way sound
- 4 bands of active EQ, tuned specifically for bass frequencies
- 5/4 string voicing switch to dial in tone for your particular instrument
- Contour control for a quick scoop-and-boost shape
- Presence control to add air and cut on top
- 2-year warranty on electronics
This is the head bassists reach for when they need reliable low-end authority night after night — whether you’re pushing a single 15, a stack of 10s, or anything in between. The active EQ and voicing switch give you real tonal range, from tight and modern to warm and vintage, without needing a pedalboard full of tone tricks. It’s not flashy. It’s just loud, clean, and dependable — exactly what you want strapped to a rack case on load-in day.
