They have a 1/8 output so I guess you could with some kind of adapter. I have the metal version perfect for playing with headphones or into a boom box just for fun
I take the 1/8 out to the aux in on a brookstone iPod boom box. You should be able to do the adapter and go 1/4 in a power amp. A pod probably would sound better. For 40 bucks the vox amplig has served me well while I wait for the ccv to arrive
