I have an Fliptop from 1963 which I love, but it is a bit finicky and not up to travel anymore. While this amp doesn't have the same style, the tone is dead on. It is a simple set of controls, sounds big, clean and loud. The DI feature (built in load box) is great, perfect for recording. If you want a classic Ampeg tone without the cost of vintage gear, this is the perfect solution.
