UL 901 Bass Amp (Gen 2)
UL 901 — Generation 2
Perfection. Only Better.
Epifani is proud to (re)introduce the UL-series professional bass amplifier — the original Epifani sound that started a revolution.
Used for decades by legendary bassists Oteil Burbridge, Anthony Jackson, and Matthew Garrison, this amp defined the modern Epifani tone.
Now, the UL 901 Generation 2 brings that legacy forward with 1000 watts of pure power, a redesigned EQ section, and the same clarity, punch, and headroom trusted by the world’s top players.
Developed in collaboration with Ron Carter, Oteil Burbridge, and Christian McBride, the UL 901 Gen 2 is a road-ready, professional powerhouse engineered to bring out your personal voice — on stage or in the studio, on electric or acoustic bass.
What’s New, EQ?
Redesigned. Refined. Remarkable.
The new 3-band Epifani EQ, featuring Mid-Cut and Treble Target controls, lies at the heart of the UL 901’s sonic identity.
Simple yet powerful, it offers up to 22 dB of boost or cut, letting you shape your tone for any venue, genre, or playing style.
Even the smallest adjustment makes a fundamental difference — precision tone control at your fingertips.
Studio Pro Grade
Your Sound — On the Record.
Heading into the studio? Bring your live sound with you.
The UL 901’s ClearTone DI Output sends a pure, full-frequency signal straight to the board — no cabinet required.
And wherever you play, the auto-sensing voltage system automatically adapts to local power, ensuring consistent performance from New York to Tokyo without risk of damage or tone loss.
