My wife and I went to Sacramento this past weekend. While there I took a road trip down to Stockton for a tour of the GK facility. WOW! What a great time. I got to meet our own Dan Elliott-- in fact he walked me around the plant. We started in the assembly room where the amps and cabs are put together and tested. There was this rack there where each amp is plugged in and run at full power for 2 hours! They do this with every amp! I was quite impressed. Each circuit (about 3000 of them) is tested 3 different times to ensure product reliability.
