We never cut corners on our guitar speakers, and we never just pull what we have off  the shelf.

amplifi ers – it’s what sets us apart from the competition. When you buy an ULTRACOUSTIC ACX450 
amplifi er, you can rest assured the speaker inside have been engineered to perform fl awlessly with 
every other element for truly professional results. 

The ACX450 features a 24-Bit FX processor per channel with 16 incredible presets including 
world-class reverb, modulation, delay and a variety of eff ects combinations. We also include our 
F112 footswitch for remote activating and deactivating the eff ects processor on either channel. 

For more than 20 years, 

 has designed and manufactured some of the most successful 

FBQ Feedback Elimination processors. Now you can own and enjoy the benefi ts of this technology, 
as we have integrated the revolutionary FBQ Feedback Detection System in this product, so your 
sound system is completely feedback-free, allowing you to focus on your performance. Utilizing 
an ultra-fast feedback detection system, this ingenious circuitry helps you recognize and tame 
feedback frequencies immediately. When feedback is sensed in a specifi c frequency range, the LED 
on the associated EQ fader illuminates, showing you at a glance which fader to lower to overcome 
the feedback. That simple!

Each channel of the ACX450 features its own 5-band EQ equipped with our amazing FBQ Feedback 
Detection System for the ultimate in feedback elimination.
