Note: all of the Groove Tubes tubes and sets we carry are "Mediums," or in the 4 to 7 range.

Groove Tubes has been manufacturing, importing, and grading quality power tubes for two decades. No stranger to Sweetwater, Groove Tubes founder and energy source Aspen Pittman has paid us numerous informative (and always entertaining) visits through the years. His tireless pursuit of perfect tube tone has resulted in Groove Tubes' reputation for consistency and premium quality. Want proof? Fender tube amps now include Groove Tubes as standard equipment, and true tube aficianados worldwide swear by the tubes and pro audio products Groove Tubes makes. For premium tube tone, choose Groove Tubes!

The GT-ECC83S preamp tube represents the classic "Euro" type tube, with medium to high gain and a linear frequency response. The GT-ECC83S gives you a very clear, even tone with good bass character. This tube type was long used as standard equipment in Marshall and Vox amplifiers. For those who change first stage gain preamp tubes to change the character of their amps (remember, this can be done in less than a minute without tools, adjustments, or a "tech"), the GT-ECC83S is definitely an essential.

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.

Offer applies only to single-receipt qualifying purchases. No interest will be charged on the promo balance if you pay it off, in full, within the promo period. If you do not, interest will be charged on the promo balance from the purchase date. The required minimum monthly payments may or may not pay off the promo balance before the end of the promo period, depending on purchase amount, promo length and payment allocation. Regular account terms apply to non-promo purchases and, after promo period ends, to the promo balance. 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.
