TIM's harp amp line out question

[Ggsound@xxxxxxx]

Tim... speaking from a "soundman's " perspective... Either let him use his own DI or you travel w/one. Just carry a short 6ft "guitar cable" to the DI and let him plug the XLR into it. I , as a sound co. , would be leery of takeing a signal from someone's "project connection " off of an amp. It takes only ONE blown mic pramp on a 5000.00 console to put a halt to unknown incoming voltage!
Good luck - Gary
