Get to know them!

Roland has made guitar synthesis easier than ever with the new GR-20 S Guitar/Bass Synthesizer. The GR-20 S makes playing high-quality synthesizer sounds from any steel-stringed electric guitar (including Les Paul-type instruments) simple! An all-new interface makes playing sounds easy using the Bank knob for sound categories and Value dial for variations, while new digital pitch detection provides superior tracking - and now bass players can tap fully into the popular GR-20 S guitar synthesizer thanks to the new Version 2 software optimized for both guitar and bass, which features the same popular patches and instant access to edit parameters as Version 1 found on the GR20. With Roland's GK-3B divided pickup installed on your bass and Version 2 loaded into the GR-20 S, bassists can enjoy a custom-tailored synth-bass playing experience and step into the forefront of the stage, where you belong.

Offer applies only to single-receipt qualifying purchases. 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.
