A feature-packed preamp designed specifically for upright players.

Stockholm, Sweden (November 6, 2020) -- With superior sound quality, powerful filters, and essential features, the new Stanley Clarke Signature Acoustic Preamp by EBS is the perfect tool to deal with all the challenges that come with amplifying acoustic instruments.

The EBS Stanley Clarke Signature Acoustic Preamp is engineered and designed by EBS together with the legendary bass player and composer Stanley Clarke. It is built with premium components exclusively.

“[This preamp] has become a mainstay to my upright bass sound. I think it is absolutely essential for every acoustic bass player to own one of these.” - Stanley Clarke

The analog 2-channel preamp uses a superior signal level quality that matches the performance of a professional-grade mixing console. The headroom and specific features make it ideal for handling the complex sonic characteristics of upright bass and other acoustic instruments.

Each channel feature a similar set of familiar EQ controls to adjust Bass, Mids, and Treble. They both also have a control to be used either as a HIGH PASS or NOTCH filter. A switch decides the function, while the control knob picks the frequency range. The notch and high pass filters are excellent tools to prevent unwanted feedback and adjust the sound to the characteristics of the room and instrument.

The two 1/4" inputs are both 10 Mohms high impedance inputs to handle both passive, active, or piezo pickups. The A channel also provides support for Electret pickups when activating a dedicated switch. The B channel, on the other hand, allows you to use a Phantom powered or passive microphone as the source via an XLR microphone input.

Jump between the A and B channel, or mix the two depending on what you prefer. A Phase Inverter switch handles any possible phase issues that may appear when mixing two different sound sources.

Other features include an EFFECTS LOOP, a TUNER OUT, a BALANCED XLR-OUTPUT with Speaker Simulator, and Ground Lift to prevent hum. An Aux Input and Headphones output makes practicing and learning new songs easy.

The Stanley Clarke Acoustic Preamp is an excellent tool also for other acoustic instruments.

Here’s a story about the most interesting man in the world.

“The guitar is my first love, my partner in life. We grew up together and we’ll most likely die together.” —Thom Bresh

One of the best benefits of being a musician is that musicians know musicians, and musicians are the most interesting people you’ll ever meet. Albert Einstein, Charles Dickens, Georgia O’Keeffe, the Marx Brothers, Clint Eastwood, Jeff Bridges, Juliette Lewis, Jack Black, and Zooey Deschanel are or were musicians, albeit not full-time.
