Hello all, I receive my LD15 x 8" yesterday via Fedex from Cali (brand new). I open the box, come to find it only came with an I-Type (Argentine) power cable. I went to the store to grab an adapter. I plug the amp in to US power, turn switch on and nothing. No light, no volume, nothing. I plug my Fender Squier bass into input jack with a new balanced cable...still nothing. Any suggestions?
