Description & Specs

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.

In The Box
UL 901 includes a custom rack-mount kit and both US- and EU-certified universal power cables.

We’re all musicians here at Chicago Music Exchange and we want you to love the gear you get from us. We understand that sometimes you get a piece of gear that doesn’t work out for you. That’s why we offer an easy return policy to take the stress out of purchasing from us.

If you decide you'd like to return an item, please contact your Sales Rep, chat us, or give us a call.

If you placed your order on Amazon or eBay, we advise issuing the return request from your account on the platform of purchase - our Customer Service team will process a refund upon receipt of the item(s).

Most new items may be returned within 30 days of delivery and most vintage & used items may be returned within 3 days of delivery for a full refund, exchange, or store credit. Please pack the product safely for the journey back to us. If the product was shipped for free, the charge will be deducted from refund, unless the reason for the return is outside normal circumstances.

Please contact us as soon as possible if your order was received incorrectly, damaged, or defective. Most times we will give you an RA number (Return Authorization). Why is that number important? This will allow us to speed up the process of the return.

We reserve the right to charge a restocking fee based on the return condition. Some items we just can’t take back for returns, due to a one time function like strings or drums heads and other times it’s not sanitary to do so with microphones or harmonicas. If you aren’t sure if what you bought falls into a category like this, call us (773) 525-7773!

We strive to get your return processed quickly. Most of the time we have it done within two business days. Funds going back to credit cards usually takes two to four business days. CME strives to make sure all customers are happy with their experience. It is our priority to provide great service along with great gear. We always want to be helpful, and open to your feedback.
