Darkglass Microtubes B7K v2 Analog Bass Preamp - Enhanced EQ | No Limit Guitar Co, Idaho Falls
The Darkglass Microtubes B7K v2 delivers the legendary B7K sound with enhanced tone-sculpting capabilities, featuring switchable center frequencies on both low and high mid bands for unprecedented EQ flexibility. This analog bass preamp combines the powerful dynamic saturation circuit of the B3K with a four-band equalizer and balanced line driver for maximum versatility. Perfect for modern bassists seeking the iconic Microtubes distortion character with expanded tonal control for studio recording and live performance applications.
Product Overview
The B7K v2 builds upon the foundation of the original B7K with significant EQ enhancements that provide even greater tone-sculpting precision. The low mids can now be switched between 1kHz and 500Hz center frequencies, while the high mids offer 3kHz or 1.5kHz options, allowing you to target specific frequency ranges that complement your bass and playing style.
The legendary Microtubes character remains unchanged, delivering the powerful dynamic saturation that has defined modern bass tone. The advanced Grunt and Attack switches provide pre-clipping tone shaping, allowing you to control exactly which frequencies enter the saturation stage for customized overdrive characteristics.
The comprehensive four-band EQ with switchable center frequencies, combined with the Blend control for clean/overdriven signal mixing, creates virtually unlimited tonal possibilities. Professional I/O includes balanced direct output and parallel output for complex signal routing in recording and live sound applications.
