One of the technical issues you get occasionally is the need to play straight through a pa, rather than an amp with a solid body guitar. Can the red box be effective in this? I see it as Guitar - pedal board - red box - Mixer. Using a mic lead from the red box to the PA. Is this too simple? Does it work., Youube tells me how great it is with an amp, or in a recording situation. 1 video mentioned in passing you could use it without an amp but it seemed he hadn't actually tried it. Apologies if this is the wrong forum. Please advise which one is right. And thanks in advance.
