Description

Edit description

Unleash the power of your Randall MTS amplifier with the Randall MTS ULTRA XL guitar amp module. This module is engineered for musicians who crave a dynamic range of tones—from pristine cleans to searing high-gain distortion. The ULTRA XL module is more than just a preamp; it's a tone-shaping powerhouse designed to elevate your sound to unparalleled heights.

Featuring a modular design, this preamp seamlessly integrates with your existing Randall RM4 preamps, RM combo amps, and RM heads. It offers intuitive control with Gain, Bass, Mid, Treble, and Master knobs, ensuring you can dial in the perfect sound for any genre. The bright switch adds a touch of brilliance to your high notes, while the two 12AX7 preamp tubes ensure your tone remains warm and rich, even at high gain settings. The modular design allows for swift and effortless swaps, letting you tailor your amp to the venue and your mood.

Whether you're jamming in your garage or rocking the stage, the Randall MTS ULTRA XL guarantees you a massive bottom end and sharp upper mids that cut through any mix. It's the perfect tool for guitarists who demand flexibility and superior sound quality from their gear.
