Massive bass thunder from a head you can toss in a backpack.
Ultra-Light, Ultra-Strong
The Bass Block is so light you might forget you are carrying it to the gig! Using an ultralight aluminum chassis, internal fan-cooled heat sink, and ferreting out every ounce possible, the Bass Block manages to pack 800 watts into a sturdy and insanely lightweight 4-lb. package.
Real-World Power at Any Voltage
Using high power technology developed for world-class pro audio touring, the Bass Block 800 delivers effortless reserves of power to maintain tight control of the speaker without clipping or bottoming out. The universal-voltage power supply delivers smooth and powerful response regardless of “club voltage” surges. The amp works on any voltage, anywhere. Plug it in, turn it up, enjoy the effortless beauty of the tone!
The Most Musical Bass Head Ever
Pat Quilter’s first amp was built in 1967 for his brother’s bass player, and great bass tone remains a key passion. The modern bass is a full-range instrument, with much different dynamic requirements than electric guitar. Low frequencies require more horsepower to move air, and the instrument demands percussive response without bottoming out or obtrusive limiting.
The Bass Block provides 800 “real watts” to build on, and the preamp is optimized to make the best use of that power, providing more effective headroom with less stress on the speakers. Unique bass-specific EQ controls allow the bassist to quickly dial in a wide range of tones to match any instrument, and a special 2-stage limiter prevents bottoming out without suppressing dynamic response and feel. A Master control allows the peak power point to be adjusted to safely power any size of speaker, from giant stacks down to compact studio units. A prolonged field testing program has confirmed that every component in the Bass Block 800 is focused on creating the ultimate musical instrument for bass players. You will feel it every moment of every gig. Effortless, powerful, and exacting tone at your fingertips.
