The all-new Rumble Series is a mighty leap forward in the evolution of portable bass amps. Re-engineered from the ground up, new Rumble amps are lighter and louder than ever, with even more power and a classic Fender vibe. A newly developed foot-switchable overdrive circuit and versatile three-button voicing palette deliver powerful tones ideal for any gig.

If there’s one thing Fender knows, it’s inspirational tone. Combining our hard-earned expertise with feedback from players around the world and brand-new technology, we created the Rumble Studio 40 digital bass amplifier. Perfect for rehearsing and recording, the Rumble Studio 40 harnesses the potent processing power of our GT engine to deliver a studio’s worth of realistic bass amp and effects models. Create your own sound and get inspired with over 15 amp models and 40 effects—all controllable via Bluetooth and the exclusive Fender Tone app.
