Hello, newby here... I use a Presonus Firestudio. I want to record a direct signal from an electric guitar, but also the live (tube)amp sound mic'd up. I don't have a DI or anything, so I've been trying stuff out. I like to record the raw clean sound, so i can always add a digital amp, or send it back to an amp, and re-record it with different settings. I've got it to work like this: Guitar>Firestudio>FX send>amp The amp got a signal, even before I opened the gain on the Firestudio. But the whole gain button didn't affect the sound at all over the amp. So I guess it's nothing to worry about. What I do worry about... Can the amp handle it? Is the signal from the send different from the raw guitar? And if so, will it hurt the amp? Or is there a different, better way to achieve this? Thanks!
