Re: What's the "line out" for?
I'll 2nd the "be careful" statement, some line outs, especially on tube amps, is taking the signal that is going to the speaker, after the power tubes! It does pad it down to line level and alot of them have an adjustment, but it still may be a little hot for a tuner. As far as it sounding like crap run to a mixer, that's what Red Boxes and other direct boxes with built in speaker sims are for.
