Grant won't even talk to you about a Psvane amp they sold, I wouldn't spend 5 cents buying anything from them.....I tried to explain that it helps the Chinese market if the seller supports the product they sell, but they don't care if they never sell another one..........I e-mailed Psvane directly and they won't answer......So before you spend more than a 100.00 on Chinese stuff, keep all this in mind...........
