Perfection. Only better.
Introducing the 2nd generation of the world-famous UL 901 bass amplifier. A modern classic with 1000W of pure power and an EQ designed to help you dial in the perfect sound. Nick Epifani collaborated with some of the world’s most accomplished bassists like Ron Carter, Oteil Burbridge, and Christian McBride. The result is a road-ready, professional powerhouse engineered to bring out your personal sound on both electric and acoustic bass.
A brand new EQ section.
The new generation of UL 901 features a redesigned 3-band EQ and mid-cut feature. Make no mistake, this is the heart of the Epifani sound. Simple yet powerful controls offer up to 22db of fine tuning to suit every venue, every style of music. Even the slightest boost or cut brings a fundamental change to your sound so you can dial in the perfect tone.
Your sound on the record.
Heading into the studio? Bring your signature sound with you. There’s no need to plug in a cabinet. Just send a signal to the board from the new ClearTone DI output and let the magic happen. And don’t worry about voltage, we got you covered there, too. No matter where you are, the auto-sensing power supply will determine the correct voltage. So there’s no chance of burning out your amp as you tour from continent to continent.
Built tough for touring.
It’ ain’t just another pretty face. UL 901 is engineered for cool, quiet, and high reliability operation. We know that when you’re on tour failure is not an option. So we built UL 901 to stand up to those bumps in the road. The jacks won’t get loose and cooling system won’t rattle around. Don’t let a lesser amp ruin your gig. You deserve great tone and peace of mind.
