Can this be done? For example could i take the Randall Diavlo Rd1 head and use the speaker emulated XLR output and run that through my Alto TS112? I know that you shouldn't run a head without a speaker to take the load but with the XLR output it has a dummy load for silent operation so to my understanding it would work. Has anyone tried this or something similar? I have a tech 21 RK5 that i play through the Alto and love it but its not exactly a high gain unit. Just wondering if i could expand and use a tube head for my heavier playing? Could run the RK into the effects loop of the diavlo as well to still use the delay etc.
