Designed in collaboration with guitar virtuoso Joe Satriani, the Peavey JSX 120W Head is a powerhouse amplifier that caters to those who demand versatility and precision. Whether you're chasing the classic warmth of a vintage British amp or the modern edge of a Triple XXX, this amp covers the entire tonal spectrum with ease. Dive into its three footswitchable channels—Ultra, Crunch, and Clean—each with its own dedicated volume and EQ controls, allowing you to switch up your sound without missing a beat.

The Clean channel offers pristine, warm tones that pair perfectly with your effects pedals, while the Ultra and Crunch channels are equipped with gain controls and fat switches for more aggressive, thunderous outputs. A fully adjustable noise gate on the Crunch and Ultra channels helps maintain clarity by minimizing unwanted noise at high settings. With four EL34 power tubes and a switchable power amp section that can also accommodate 6L6GCs, the JSX is designed to deliver a staggering 120 watts of tube-driven power.

Global resonance and presence knobs provide additional tonal shaping, allowing you to adjust high-end frequencies to suit any performance space. The built-in effects loop, complete with send and return controls, ensures seamless integration of your favorite pedals.
