Unleash the True Power of Your Bass
Ready to take your bass tone to the next level? The ZUTA BASS CORE is a professional two-stage preamp and tone-shaping circuit that brings your low frequencies out of the shadows and into the spotlight.
Experience studio-quality sound with a simple, ergonomic installation directly inside your bass.
Dial in Your Perfect Tone
Take complete control of your sound with three intuitive center detent knobs: bass, mid, and treble. Plus, with 6 built-in DIP switches, you can precisely set the mid frequency to shape the perfect curve for any style.
Whether you need to create a thunderous, powerful low end or cut through a dense mix with clarity, the BASS CORE gives you the tools to find your unique voice.
When all knobs are set to neutral, the preamp should be completely transparent, with a maximum deviation of ±0.5 dB across the 20 Hz – 20 kHz range.
Simple and Powerful
Powered by a 9 to 18V supply (like one or two 9V batteries), this compact circuit offers professional-grade amplification and tone shaping in a seamless package.
Elevate your performance and let your low end be heard.
The component choices have been made with the aim of achieving low power consumption, good headroom, and low distortion/noise.
