THE CULMINATION OF 30 YEARS OF INNOVATION
The ES 4 features four newly designed high-definition MAX-HD mic preamps with +75 dB of gain - making it ideally suited for today's most popular microphones. Guitarists and bassists will love the instrument inputs, which were co-developed with Fender engineers.

And bright and responsive LED metering provides easy visual feedback for your inputs and outputs, making it great for self-produced recording.
