The End to Your Signal Loss Problems

This article was Written By

Get to know them!

When Sweetwater tested out the Empress Buffer+ pedal, we could visibly see those 50-foot cable runs quaking in their boots. Pesky tone loss can no longer compete — now you can retain the full power of your signal over longer cable runs with this powerful pedal that is designed as a complete I/O interface for your board. What makes the Buffer+ so special? Its all-analog signal path contributes to dynamic response and superb signal passage. Plus, its minuscule size and flat top make a small footprint on your pedalboard, which means more room for phaser, tremolo, delay, and overdrive! To tie it all together, the Buffer+ also provides a separate tuner output to keep it away from the main audio path.

Unique features with the Buffer+

Other buffer pedals make way for the Buffer+! This rad buffer has all the same high-fidelity signal as the original Empress Buffer but with added features that make it a powerful tool for any pedalboard. It all starts with a switchable boost that can add up to 30dB of clean boost via a soft touch foot switch. Next, use the noise filters to remove unwanted noise from the effects chain and use the tuner mute to quietly tune while on stage. An input pad can pad or boost the input by three dB — a great help for matching guitar outputs or tempering really hot active pickups. Lastly, an input loading knob allows you to load down your pickups however you want.

Empress Buffer+ Pedal Features:

  • Reduce the signal loss from long cable runs
  • Functions as a complete I/O interface for your pedals
  • All-analog circuitry contributes to dynamic response
  • Small footprint with the ability to mount on the back of your pedalboard thanks to a flat top
  • Separate tuner output to keep tuning away from main audio path
  • 2 different noise filters reduce unwanted noise from the effects chain
  • Input pad can pad or boost input by 3dB
  • Input loading can load down your pickups
  • Tuner mute footswitch mutes the amp output

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.
