A vocalist’s best friend.

Vocalize and jam with powerful voice transformation tools, high-quality effects, and an onboard looper. 

The E-4 Voice Tweaker is an outrageously jammable box of fun that harmonizes, auto-pitches, vocodes, loops, and glitches your voice and anything else you feed it. Flip through hands-on controls to manipulate the sound, and chain in AIRA Compacts and other electronic instruments and let them ride in perfect sync.

Explore the AIRA Compact series.

Inspiring Roland vocal processing.

The E-4 combines powerful voice transformer tools and standard vocal effects with a tactile interface that’s meant to be played. This lean, mean machine puts a treasure trove of top-quality processing in a go-everywhere gadget that’s endlessly enjoyable and amazingly affordable.

Perform with sound.

By working the E-4’s inviting panel, you can go from traditional vocal enhancements to punchy beatboxed grooves to striking alien soundscapes—all in a single performance. Select different sonic shapers, trigger looper controls, cycle through Scatter effects, and tweak pitch, formant, and more in the flow.

Harmonic explorer.

Take your singing to the next level with automatic harmony effects. Set the key and chord voicing on the fly and bring head-turning flair to any song. And with Auto Pitch, you can dial in everything from subtle tuning fixes to the hard-tuned sounds heard in mainstream pop tracks.

Channel your inner robot.

Use direct-access tools to instantly change your vocal gender, conjure sounds from outer space, or transform yourself into a mechanical persona (good or evil is up to you). There’s also a powerful vocoder, which you can drive from a large pool of onboard synth waveforms, the E-4’s pitch functions, or an external MIDI keyboard for an endless variety of textures.

Loop and Scatter.

Turn one voice into an entire orchestra using the 24-second looper. Overdub layer after layer with the E-4's effects to create wild, vocal-driven rides. Then slice and dice with the expressive Scatter knob, which chops your sound into colorful bits that you control with a twist.

Link up and go.

Connect a handheld mic to the front input for performing, or use a gaming headset or the inline mic on your earbuds to bring fresh vocal fun to your next livestream or podcast. Sync with other AIRA Compacts like the T-8 Beat Machine and J-6 Chord Synthesizer to expand your range. Or interface with computer DAWS, mobile music apps, and hardware instruments via USB-C or MIDI.

Everywhere at once.

The E-4 creatively accentuates vocals anytime and anywhere. The lithium-ion battery provides up to 3.5 hours of power per charge, and the rugged Roland build will support inspired magic and mayhem for a long, long time.

    CPS Extended Warranty

    Warranty Information

    PROTECT YOUR PRODUCT WITH AN EXTENDED WARRANTY

    • Full Coverage from Date of Purchase
    • 100% Parts and Labor Coverage
    • Includes Accidental Damage
    • Includes Free Shipping
    • Up to 5 Years of Total Coverage

    Bananas has partnered with Consumer Priority Service (CPS) to offer extended warranties for your instruments. Simply add the CPS extended warranty by selecting the option on our product pages.

    Warranty FAQ

    DO I NEED AN EXTENDED WARRANTY?

    Most manufacturers limit their warranty periods to keep their product costs competitive. It should come as no surprise that most problems occur after the manufacturer’s warranty is over. If you are like most consumers, you don't want to deal with the inevitable problems surrounding repairs. Who do you call for service? Are they reliable? Is a handyman capable of performing a long lasting, reliable repair on your instrument?

    Ranked #1 Extended Warranty

    CPS provides top notch warranty protection for your purchases to ensure life and longevity. This means that they care about you and your product long after your purchase has been made. This warranty offers reliable, hassle-free, comprehensive parts and labor protection for your product.

    You Need to Prepare for These Issues Today

    Bananas is an Authorized Consumer Priority Service Dealer. This means that they care about you and your products long after the purchase date. You can easily extend your manufacturer's warranty for a possible total of 5 years from the date of purchase.

    CPS Warranties Offer Reliable Protection for Your Product

    By purchasing a CPS accidental damage plan, you’re guaranteed years of worry free operation from your new product.

    Is a CPS Warranty just an extension of the existing manufacturer’s warranty?

    Actually, it’s an upgrade to your existing manufacturer’s warranty. A CPS Warranty offers benefits that aren’t offered by manufacturers like accidental damage & free shipping to and from the repair facility.

    What’s the difference between a Replacement Plan and Repair Plan?

    A Replacement Plan is available for products under $150. If the product fails, you will receive a replacement through Bananas.

    A Repair Plan is for products over $150 and offers free repair coverage for your product any time during the life of your warranty. If we can’t fix it, we’ll replace it!

    How am I covered?

    For the Replacement Plan, your coverage provides for a one-time replacement of the covered product.

    For the Repair Plan, you are covered for a period of up to five years (depending on which plan you purchase). Benefits include parts and labor for required repairs on your product.

    When does my warranty coverage start?

    Coverage begins on the 31st calendar day from when you purchased your product.

    Can I transfer the Protection Plan to a new owner?

    Yes! CPS Warranties are transferable between owners.

    What if I Need to Return my Product?

    If you return your product, Bananas returns the money you paid for the product protection plan. Depending on how much time has passed since your purchase, CPS may issue a prorated refund.

    Is my product covered if it’s stolen or if I lose it?

    Unfortunately the CPS Warranty does not cover lost or stolen products.

    Is there a service fee?

    Zero dollar service fee for the Replacement Plans and the Repair Plans.

    HOW DO I FILE A CLAIM?
