What questions should I have asked? Clearly I was ready to purchase the amp for the price I offered (which was accepted) based on the information which was provided in the UNREVISED listing. ANYBODY would have assumed by the original listing it was a USA Amp....not a grey market 240V amp. You also would have assumed that the amp was coming from the seller in California....not from somebody 3000 miles away in Massachusetts. It was only AFTER my offer was accepted that all these "New" details were brought to my attention in a separate message from the seller about the voltage change, who the owner of the amp REALLY was and where he lived etc
In case you arent aware if you buy a Grey Market Amp you will be refused service by the manufacturer should anything go wrong with it down the road.
