I've been considering getting a Traynor YCV50BLUE. I had also checked out the YCV15BLUE and I realized it had a button on the back to kill the speaker, I guess that means so that you can run the line out, or run the amp into say a 4x12 cab. I'm wondering if there is any sort of dummy load that could be wired in between the speaker and the poweramp, which could be turned on when needed. This way I could wire the external speaker out, into whatever speaker I want.
