For just a good basic tone I can Tweak I like the Cyber Twin Better than the Fractal. IMHO the CT sounds Better than the Fractal but cant do nearly the combinations of effects nor does it have as many. The Fractal Distortion Still sounds like SOLID STATE.. The Fractal Effects are as good or better than the CT. CT just doesn't have nearly as many nor can you combine them like the Fractal. The ability to combine effects on both the Fractal and Kemper are Unsurpassed. Im thinking of selling the Fractal and just buying the New Fractal FX8 Pedal Board. AXE FX and Kemper Effects are about the same from what I can tell. Both are GREAT. Im not a Tube Snob by any means but if it comes down to it Ill pick Tubes everytime. CT also has a Tube Preamp. 2 x 12AX7 was Standard but I replaced them with NOS Mullard Master series Gold PIN 10M 12AU7's. Clapton used 2 Sunn Coliseum Lead Heads and at least 1 x 4 x 12 Sunn Cabinet on the Derek ad the Dominoes Live album they did at the Fillmore. This 1 isn't mine but is a better photo than I have.
