Get to know them!

The Zoom B1X FOUR bass multi-effects pedal takes your low end to new heights with over 70 effects and amp models, a looper, a built-in rhythm section, and an expression pedal. It also includes access to Zoom Guitar Lab’s extensive library of downloadable artist patches and effects. Forge your signature sound with more than 70 classic and boutique effects, such as octaver, fuzz, and bass synth. Recreate your onstage tone with nine classic amps and cab combinations, including Fender, Aguilar, Ampeg, and more. Lay down a bass line of up to 30 seconds, and then endlessly overdub your performance to build a dynamic, multi-part arrangement.

Packed with features for the modern bassist

The Zoom B1X FOUR’s onboard drum machine lets you play your bass to 68 different drum patterns in a variety of time signatures, such as 4/4, 3/4, and more. For live performances, two performance modes allow you to switch patches and effects seamlessly. At home or in the studio, put your pedal on the desktop to easily dial in your sounds and settings — the auto save function instantly backs up your patches and level settings as you create them! The B1X FOUR operates on four AA batteries or the optional Zoom AD-16 AC adapter; you can even run your pedal via USB bus power.

Select manufacturers may require that only the manufacturer’s products qualify towards the minimum purchase amount needed to be eligible for promotional financing. Otherwise, an invoice that meets the minimum purchase amount and contains at least one qualifying manufacturer product is eligible for promotional financing. No interest will be charged on promo purchase balance, and equal monthly payments are required on promo purchase until it is paid in full. The payments equal the amount financed divided by the number of months in the promo period, rounded up to the next whole dollar. These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases. New Accounts as of 07/31/2025: Purchase APR is 34.99%. Penalty APR is 39.99%. Min Interest Charge is $2. Existing cardholders: See your credit card agreement terms. Subject to credit approval.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
