I'm planning on getting an elec. Acoustic guitar- can I plug that into my regular amp? I have a line 6 spyder III... or iif not I do have a mixer which I have my mic plugged in-- think would work

Your electric acoustic can be treated the same as a normal electric yes you can plug it into your normol amp and get amaizing sound (p.s. I have a line 6 spider II) and B. you can plug it into your mixer with your mic but a guitar will put out more power therefore will distort way easier in the mixer. It will work in the mixer but the volume on the mixer itself will have to be low, unless the mixer has a separate line in and doesn't just say mic. All in all yes your electric acoustic will work in BOTH your amp and mixer but you are way better to use your amp.. hope that helped bud have a nice day
