BOSS Ultimate Blues Tone Capsule Modification Circuit for Blues Cube Stage, Artist, Artist212, and Tour Guitar Amplifiers with Kirk Fletcher Signature 6V6-Inspired Voicing (BC-TC-UB)

The BOSS BC-TC-UB Ultimate Blues Tone Capsule is a premium amplifier modification circuit designed to customize the tonal character and response of compatible Blues Cube guitar amplifiers. Developed under the supervision of renowned blues guitarist Kirk Fletcher, this Tone Capsule delivers the warm compression, smooth breakup, and soulful dynamics of classic small 6V6 tube amplifiers while maintaining the powerful output capability of the Blues Cube platform.

Installed directly into the amplifier’s Tone Capsule socket, the BC-TC-UB modifies the internal Tube Logic characteristics of the Blues Cube to create a more vintage-inspired blues voice. It recreates the sweet, deep compression and expressive response of fully driven small blackface-style amplifiers, providing rich clean tones and smooth crunch sounds ideal for blues professionals.

Unlike traditional low-wattage 6V6 amplifiers, the Blues Cube equipped with the Ultimate Blues Tone Capsule maintains enough output power for stage performance while delivering the feel and tonal character associated with classic blues recordings.

Compatible with Blues Cube Stage, Blues Cube Artist, Blues Cube Artist212, and Blues Cube Tour amplifiers, the BC-TC-UB provides guitarists with an instant professional-grade tonal transformation.
