Wasn't this one of the reasons for developing humbucking pickups? It would be useful to try more than one guitar in the amplifier, and connecting lead too. I think guitar amplifiers has things like prescence controls etc which when turned up provoke hum pickup and put the guitar on the point of feedback, although the user would likely be aware of this. If the guitar was initially faulty though it may not have been obvious.
