Hughes & Kettner CoreBlade Tube Set

The Hughes & Kettner CoreBlade Tube Set consists of 3 x 12AX7 preamp tubes and 4 x EL34 Power Tubes in a matched quad.

Hughes & Kettner CoreBlade amp head is the flagship of Hughes & Kettner’s line of programmable tube amps. 4 independent channels, 3 parallel FX modules, an intelligent noise gate, automatic power tube management, and analog programming technology add up to an awe-inspiring arsenal of merciless sounds.

The the Hughes & Kettner Coreblade’s Tube Safety Control (TSC) is a power tube management circuit that automatically biases the amp to ensure stable sound and long tube life. It also shuts down defective tubes to get you through the gig, and indicates ratings to make tube selection an exercise in convenience. TSC even lets you run EL34 and 6L6GC tubes simultaneously. Tube tone customizing doesn’t get any easier or more gratifying than this.
