Get to know them!

Ever dreamed of having the perfect pedalboard setup with multiple path routing options and pristine audio quality? Enter the Empress Effects Buffer++, your solution to bring your complex pedalboard rig aspirations to life. The Buffer++ is built not only to be your main signal chain hub but also to restore and refine your incoming and outgoing signals, ensuring your amp — or amps — get the best possible tone. Its all-analog design keeps your guitar rig’s signal pure with zero latency, while input and output metering lights provide immediate visual feedback for your signal strength. Moreover, you get adjustable Pad and Noise Filter switches per input, switchable clean boost of up to 30dB, variable input loading, and a separate Tuner Out with Tuner Mute for silent tuning between songs in your set. With dual inputs and outputs that can be configured to run mono or stereo, the Buffer++ is primed to be your centralized hub for all your signal management needs.

Fine-tune your tone

Any Sweetwater pedalboard designer will attest to the need for high-quality signal flow in any-sized rig and highly praise the Buffer++ for its tone preservation and boosting capabilities. Each input includes two different degrees of noise filtering through their respective loops, canceling out any unwanted higher frequencies from your pedal chain. Next, the Pad selector switches between 0dB, -6dB, and -12dB at each input — perfect for providing signal balance between two different instruments or varying pickup strengths from each guitar. For vintage tone enthusiasts who prefer the high-frequency roll-off that occurs with long cable runs, the Input Loading control can dial those frequencies out while maintaining optimal signal flow.

Empress Effects Buffer++ Features:

  • Stereo I/O solution and buffer pedal with selectable boost and signal routing options
  • Internal buffer circuit revitalizes guitar tone due to long cable runs
  • All-analog circuitry preserves signal integrity throughout your rig
  • Input meters provide a visual confirmation of signal strength
  • Up to 30dB of clean boost accessible via footswitch
  • 2 different noise filters per input reduce unwanted noise from your FX chain
  • Separate tuner output to keep your pedal tuner away from the main audio path
  • A/B or A/Y signal routing allows switched mono or stereo signal chains to amps or outboard gear
  • Built-in noise filters eliminate high-frequency noise within the Loop circuit
  • Input pads to complement differences in guitar or signal path output
  • Input loading control sets high-frequency pass-through
  • External switch output can control tuner mute with an external pedal switcher

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.
