I only know what I've read about them and that's all been positive.
I think that the "Line 6 Pod" is the "professional choice" retailing a little under £300. I don't know how that compares with the V-Amp.
I'd be interested if anyone can explain the best way to incorporate these gadgets into a live set-up. I understand that you can D.I. straight to the P.A. but would you then use your existing guitar amp as a monitor and would that "colour" your gadgets sounds.
I hope I'm not hijacking your thread, Ireland, presumably some discussion on the workings of these things is welcome.
C-flat.
