Signature Acoustic Preamp Pedal

Designed By EBS & Stanley ClarkeThe Stanley Clarke Signature Acoustic Preamp is a 2-channel preamp, built strictly with premium components. It is engineered and designed by EBS in conjunction with the legendary bass player and composer Stanley Clarke. The preamp provides a huge amount of headroom as it operates at a signal level equal to professional mixing consoles. The fantastic signal quality makes it suitable to use as a preamp alongside any power amp. The headroom and unique features make it perfect for handling the diverse sonic characteristics of an upright bass.
Amazing Features
• XLR microphone-input with Phantom Power (channel B)
• Individual High Pass/Notch Filter for each channel
• 10 Mohm Impedance inputs (both channels)
• Operates with Studio-grade signal quality
• 2-channel analog preamp (A/B or A+B)
A Secret Weapon

Two ChannelsThe A and B channels both come with an input GAIN control and an EQ strip with BASS, MIDS (pick the frequency range with one knob and cut or boost in that range with another) and TREBLE. They also both come with a secret weapon, a control knob that can be used as a HIGH PASS or NOTCH filter.
The switch choses the function, whilst the control knob selects the frequency range. The notch and high pass filters are brilliant tools that prevent unwanted feedback and adjust the sound to the characteristics of the room and your instrument.
Seperate Input Options

Practical FeaturesThe 10 Mohms input impedance for both the A and B channels means it can handle any instrument with passive, active, or high impedance piezo pickups. The A channel also provides support for Electret pickups when selecting the dedicated switch.
The B channel lets you use a 48V Phantom powered (or passive) dynamic or condenser microphone as the source via an XLR-input. Choose whether to use the XLR or 1/4"-input for the B channel with a switch.
The preamp allows yout to jump between the A and B channels to allow for different settings when you play with a bow or pizzicato or mix the two if you use two different input sources. Blending two different sound input sources can sometimes cause a phase issue. If this problem happens, you have Phase Inverter switch, attached to the A channel which will fix this.
Outputs & Additional Features

As Versatile As It GetsYou can attach additional effects in serial or parallel using the effects loop (requires a Y-split insert cable). A tuner out lets you plug in an external tuner, and the balanced XLR-output sends a studio-quality line signal to front-of-house or a recording device.
You can use it with a Speaker Simulator and use the Ground Lift to eliminate hum. The Aux Input and professional-grade Headphones output makes practicing and learning new songs simple and easy.
Works With Multiple Instruments

Anything Is PossibleThe frequency range of an upright bass is wide and diverse, this means most other instruments, acoustic or electric fit within the range that this pedal can cover. Other acoustic instruments benefit from the same specific features that this pedal is equipped with to handle the upright bass.
Electric bass players may find the two similar channels an excellent way to make separate EQ settings for two individual instruments and make it possible to switch between the two seamlessly whilst performing.
