Fender Rumble™ Studio 40 Fender

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.

As the world’s first WiFi-equipped bass amplifier, Rumble Studio 40 makes it easy to explore contemporary sounds and update your palette for new sonic possibilities. With the Fender Tone app, it’s easy to download the latest updates, add new amp and effects models, access Fender artist-created presets, and connect directly with a community of other creative players and music makers.

It’s virtually impossible not to get inspired while playing this amp. Packed with classic amp models—everything from the renowned ’59 Bassman models to monster rigs of the ‘70s and ‘80s and the best modern bass amps—the Rumble Studio 40 can easily recreate classic tones. We also included over 40 studio-quality effects; ranging from delays and reverbs, compression and EQ, to bass-specific favorites like octave effects, an envelope filter and Octobot synth emulator, these effects make it easy to craft brand-new sounds.

We developed new amp and effects models with even higher fidelity and more realistic response, along with more signal path flexibility so you can move effects anywhere in the signal chain for creative exploration. Program your sounds in the studio on the Rumble Studio 40’s large, full-color LCD display and then take them anywhere.

No matter how good your amplifier sounds, you need speakers that can accurately reproduce your tone, and the Rumble Studio 40’s 10” woofer and switchable compression tweeter are more than up to the task. XLR line outputs and onboard USB output, along with Bluetooth audio streaming for playing along with backing tracks and a headphone output make this amp at home in any environment—stage or studio. Adding the optional MGT-4 4-button footswitch or GTX-7 7-Button Footswitch for preset/FX switching and looper control turns the Rumble Studio 40 into a truly formidable performance powerhouse.

Master your tone and create any sound you can imagine with the Rumble Studio 40, the latest evolution of our world-famous bass amplifiers.
