Picked up a Markbass TTE 500 this week. This is my first tube amp in decades, (like three decades), and I was knocked on my butt by how punchy and aggressive this puppy sounded. Im using it with a Bergantino AE410 and a Spector Euro 4 LX with nickel wound strings. It was the end of the night and it was hot and we were tired etc, so the playing itself is on the sloppy side*, but I think this video is an accurate representation of what this unit plays out like. I had the gain set at 1:00, the master at 10:00 and the compressor at 12:00. Enjoy! http://youtu.be/3I-FeheI_F8?t=26m20s *I say that in all the videos I post on TB in a weak attempt to divert attention away from my crappy bass playing lol!
