Epiphone Valve Std.

These amps have some major noise issues.  To tamp it down, I cut a few sensitive circuit PCB traces and wired those connections underneath the board with shielded wire.  I also added a true-bypass switch for the DSP circuitry, which cut noise but also improved the tone.

I made a few changes to the DSP portion of the circuit too (to reduce noise) and turned the preamp into something very similar to that of an AC30 top-boost.
