Stanley Clarke Signature Preamp
Stanley Clarke Signature Preamp
EBS Stanley Clarke Signature Acoustic Preamp. Precision-crafted for upright bass and beyond.
Co-designed with bass legend Stanley Clarke, this 2-channel preamp delivers studio-quality tone, unmatched filtering, and smart flexibility for acoustic instruments—especially upright bass.
Professional-Grade Performance:
Runs at console-level for superior headroom and clarity
Optimized to handle the complex tone of upright bass
Built with premium components for maximum fidelity
Dual Channel Power:
Independent EQ with sweepable mids, bass & treble
Switchable High-Pass or Notch filter per channel for feedback control
Blend or toggle channels—ideal for mixing pizzicato and arco styles
Flexible Inputs:
Works with passive, active, and piezo pickups (10 MΩ impedance)
Channel A supports Electret pickups; Channel B accepts 48V phantom-powered mics or ¼″ inputs
Phase Inverter on Channel A to address blending phase issues
Connectivity & Utility:
XLR out with speaker sim, ground lift, and FOH-ready signal
Effects loop, tuner out, aux in, and pro-grade headphone out
Use in serial or parallel FX mode with a Y-split insert cable
Note: Early units have always-on phantom power—avoid passive ribbon mics via XLR
Also ideal for other acoustic and electric instruments. Electric bassists benefit from two EQ setups and seamless instrument switching on stage.
